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.

        -- BUG-FIX: Some keywords were accidentally joyned together. Now fixed.
    - v.1.1 (2017-04-30)
        -- Updated to PureBASIC 5.60.
        -- Keywords list now built by extracting them from the PureBASIC SDK's
           "SyntaxHilighting.dll" (from each PureBASIC version). Tokens from each
           version are added to the list, and renamed or removed tokens are kept
           for the sake of covering all versions of the language from PureBASIC
           v5.00 upward. (NOTE: currently, there are no renamed or deprecated
           tokens in the keywords list). For more info, see:
           -- http://www.purebasic.fr/english/viewtopic.php?&p=506269
           -- https://github.com/tajmone/purebasic-archives/tree/master/syntax-highlighting/guidelines
    - v.1.0 (April 2016)
        -- First release
        -- Keywords list taken and adapted from GuShH's (Gustavo Julio Fiorenza)
