Subject: plproxy - plproxy: Make scanner accept dot as standalone symbol
Date: Mon, 29 Jun 2009 13:37:58 +0000 (UTC)
Message-ID: <20090629133758.48FA21072079@pgfoundry.org> (raw)

Log Message:
-----------
Make scanner accept dot as standalone symbol

Currently PL/Proxy fails to parse following query:

  select (ret_numtuple(1)).num, (ret_numtuple(1)).name;

The fix is to add "." to the SQLSYM rule in the lexer.  This should be OK
because an identifier chain will always be longer than a single dot, so flex
will prefer it over parsing the single dot.
