PostgreSQL + SQLite support is stabilized,

identifiers like table name + column name + alias are parameterized + made case-sensitive for PostgreSQL + SQLite by quoting them in double quotes,
upsert is patched for PostgreSQL and SQLite,
code optimized to use string interpolation instead of concatenation,
like + in prefixes and suffixes combined into 1 object look up function 'prefix',
join object 'using' property optimized to handle placeholders and names,
prepSubStr + prepPadding functions created for better code reusability and maintainability,
replace property keywork 'with' renamed to 'replaceWith' for better understanding and readability,
cast wrapper in prepNumeric moved to outer level to support casting into decimal etc after mathematical operations are done,
prepName helper optimized for better code execution,
prepPlaceholder helper optimized to support wrapping column names in double quotations,
ctx patched to all prepName invocations to support wrapping column names in double quotes,
code cleanup
