Обсуждение: pgsql: Fix restriction on specifying KEEP QUOTES in JSON_QUERY()

Fix restriction on specifying KEEP QUOTES in JSON_QUERY()

Currently, transformJsonFuncExpr() enforces some restrictions on
the combinations of QUOTES and WRAPPER clauses that can be specified
in JSON_QUERY().  The intent was to only prevent the useless
combination WITH WRAPPER OMIT QUOTES, but the coding prevented KEEP
QUOTES too, which is not helpful. Fix that.
