fix: enable the markdown extensions our imported sources rely on - #168

Conversation
Three pages on the live site show raw markdown instead of the pgEdge Labs
banner: /pgedge-safesession/v1-0/, /pgedge-mcp-bridge/development/ and
/pg-semantic-cache/development/. All three wrap the images in
`<div class="banner" markdown>` and size them with `{ width="320" }`, which
need md_in_html and attr_list. Those repositories declare both; this one
declared neither, so the div's contents were emitted untouched.
The general point, which the comment now records: this list has to be the union
of what every imported source declares, not just what docs/ needs. Their
content is frozen at tags we cannot amend, so an extension they rely on and we
do not enable renders as literal text. Across the imported refs, attr_list is
declared by 76, md_in_html by 76 and def_list by 72.
def_list is the one with reach. It fixes roughly 1,980 pages, most of them
PostgreSQL, which currently render definition lists as paragraphs with a
literal colon: the acronyms appendix reads "AIO : Asynchronous I/O" today and
becomes a proper dt/dd list.
Against that, seven pages regress slightly. pgedge-loadgen and
pgedge-postgres-mcp-server have stray `{% raw %}`/`{% endraw %}` markers left
in their markdown, and attr_list now consumes the closing one as an attribute
list, so a paragraph gains `_="%" endraw="endraw"`. Those markers are an
upstream authoring mistake either way: today both render as visible junk text,
afterwards the closing one becomes junk attributes instead. Worth an upstream
issue rather than a reason to leave 1,980 pages broken.
Verified by building both ways: 17,367 files on each side, 2,007 pages differ,
and every one is accounted for. The three banner pages now emit img elements,
roughly 1,980 gain definition lists, ten are the redoc pages with their usual
per-build random id, seven are the attr_list artefact above, and one is the
Pagefind entry manifest.
WalkthroughThe import pipeline now retains Markdown extensions from imported sources, merges compatible bare extensions into the parent MkDocs configuration, and reports configured conflicts. The configuration documentation reflects this behavior. ChangesMarkdown extension reconciliation

Replaces the hand-maintained list from the first commit on this branch.
Hand-maintaining it is exactly how the reported bug happened: nobody updates
mkdocs.yml when a new docset imports content that needs an extension we do not
have, so the gap only surfaces as a broken page in production. This makes it
self-correcting instead.
scripts/expand_imports.py already parses every source's mkdocs.yml for its nav;
merge_markdown_extensions reads markdown_extensions from the same object. A
*bare* extension (no config) absent from ours is added automatically: enabling
it cannot change how any other page renders, since it has no config to disagree
about. A *configured* one is reported rather than merged, because
markdown_extensions is one global list for the whole site, so guessing whose
config wins is a site-wide decision a human should make, not this script.
Concretely, today that is 5 added (attr_list, def_list, md_in_html, meta,
tables — two more than the previous manual list found) and one reported: an
imported pgedge-loadgen ref enables `toc: {permalink: true}`, which we do not
have at all. Nothing renders wrong from that today, since MkDocs already runs
toc internally for its own heading ids regardless of markdown_extensions, so
the config only controls the permalink icon; it is a site-wide styling
decision, not a fix, and the warning says so.
mkdocs.yml goes back to declaring only what this repository's own pages need,
with a comment pointing at the script and telling a reader how to see what it
currently adds.
Verified by building and diffing against the pre-fix baseline: 17,367 files on
both sides, 2,009 pages differ. All but two are explained exactly as in the
previous commit (~1,980 gain definition lists, 3 are the reported banner pages,
10 are redoc's per-build random id, 7 are the attr_list artefact on stray
{% raw %} markers, 1 is the Pagefind manifest). The remaining two,
pgedge-postgres-mcp-server and pgedge-rag-server's development changelogs, are
upstream content drift: both are `development` refs, and each repository
gained new changelog entries and, for pgedge-postgres-mcp-server, a repository
rename, in the time between the baseline build and this one. Neither diff
contains anything markdown-extension shaped.

Do not treat bare extensions as render-isolated.
A bare MkDocs extension changes parsing for the complete generated site. The PR comparison already identifies seven attr_list regressions in local template markers. Fix or escape those markers before this function enables attr_list globally, and add a generated-output regression check for them.

Add bare occurrences when another source configures the same extension.
If one imported source declares tables and another declares tables: {...}, configured is non-empty. This branch reports the configured occurrence but does not add tables, so the bare source still renders without its required extension. Report configured occurrences, but append the extension when at least one occurrence is bare.
Proposed fix
configured = [(label, cfg) for label, cfg in occurrences if cfg is not None]
if configured:
for label, cfg in configured:
conflicts.append((name, label, cfg, "not enabled here at all"))
- else:
+ if any(cfg is None for _, cfg in occurrences):
added.append(name)📝 Committable suggestion
‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

The reported bug
Three live pages show raw markdown where the pgEdge Labs banner should be:
The images themselves are fine and return 200; the markdown simply never
renders. All three sources wrap them in
<div class="banner" markdown>, whichneeds
md_in_html, and size them with{ width="320" }, which needsattr_list. Those repositories declare both. This one declared neither.The general point
markdown_extensionshere has to be the union of what every imported sourcedeclares, not just what
docs/needs. Imported content is frozen at tags wecannot amend, so an extension a source relies on and we do not enable renders as
literal text. Across the imported refs:
attr_listdeclared by 76,md_in_htmlby 76,
def_listby 72, and we had none of them. There is now a comment sayingso, because the next person to prune this list will otherwise reintroduce the
bug.
What changes, and it is more than three pages
2,007 pages differ, all accounted for:
dt/ddinstead of paragraphs with a literal colon{% endraw %}consumed byattr_listdef_listis the one with reach, and it is a real improvement. The PostgreSQLacronyms appendix currently reads
AIO : Asynchronous I/Oas a paragraph with avisible colon; it becomes a proper definition list. Most of the 1,980 are
PostgreSQL, with postgis, postgrest, cloudnativepg and psycopg2 behind it.
The regression, in full
pgedge-loadgenandpgedge-postgres-mcp-serverhave stray{% raw %}and{% endraw %}markers left in their published markdown. Withattr_listenabled, the closing marker is read as an attribute list, so a paragraph gains
_="%" endraw="endraw":Seven pages, listed in the commit message. Those markers are an upstream
authoring mistake either way: today both render as visible junk text, afterwards
the closing one becomes junk attributes instead. I would rather raise that
upstream than leave ~1,980 pages rendering definition lists as prose, but say so
if you would prefer
attr_listheld back until the sources are fixed — the threereported pages need
md_in_htmlandattr_listtogether, so holding it backmeans not fixing them.
Verification
Built both ways from the same tree: 17,367 files on each side, and every one of
the 2,007 differing pages classified rather than sampled.
