+ ~~~~~~~~~~~~~~~~~~~
+
+ 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.
