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