1. Added "--default foo" style comments to new PL/pgSQL function parameters
because xotcl-core, rather than use the metadata created by define_function_params,
ASSIGNS SEMANTICS TO THESE SQL COMMENTS. Bah. If I truly cared about quality
I'd insist the xotcl people fix their code and do things right, but I know that
would never happen so ... kludge away.
2. xotcl-core adds CR attributes (rather than fix core). So my fixing of
core conflicts, meaning I have to kludge again. Still needs to be fixed
for oracle.
