Language: PostgreSQL and PL/pgSQL
Author: Egor Rogov (e.rogov@postgrespro.ru)
Website: https://www.postgresql.org/docs/11/sql.html
Description:
This language incorporates both PostgreSQL SQL dialect and PL/pgSQL language.
It is based on PostgreSQL version 11. Some notes:
- Text in double-dollar-strings is _always_ interpreted as some programming code. Text
in ordinary quotes is _never_ interpreted that way and highlighted just as a string.
- There are quite a bit "special cases". That's because many keywords are not strictly
they are keywords in some contexts and ordinary identifiers in others. Only some
of such cases are handled; you still can get some of your identifiers highlighted
wrong way.
- Function names deliberately are not highlighted. There is no way to tell function
call from other constructs, hence we can't highlight _all_ function names. And
some names highlighted while others not looks ugly.
