    ~~~~~~~~~~~~~~~~~~~

    Lexers for various SQL dialects and related interactive sessions.

    Postgres specific lexers:

    `PostgresLexer`
        A SQL lexer for the PostgreSQL dialect. Differences w.r.t. the SQL
        lexer are:

        - keywords and data types list parsed from the PG docs (run the
          `_postgres_builtins` module to update them);
        - Content of $-strings parsed using a specific lexer, e.g. the content
          of a PL/Python function is parsed using the Python lexer;
        - parse PG specific constructs: E-strings, $-strings, U&-strings,
          different operators and punctuation.

    `PlPgsqlLexer`
        A lexer for the PL/pgSQL language. Adds a few specific construct on
        top of the PG SQL lexer (such as <<label>>).

    `PostgresConsoleLexer`
        A lexer to highlight an interactive psql session:

        - identifies the prompt and does its best to detect the end of command
          in multiline statement where not all the lines are prefixed by a
          prompt, telling them apart from the output;
        - highlights errors in the output and notification levels;
        - handles psql backslash commands.

    The ``tests/examplefiles`` contains a few test files with data to be
    parsed by these lexers.
