Thanks Alvaro.
Didn't find any good examples in the archives (looked there before
asking here), even though there are a few people over time asking the
same question.
In PL/pgSQL at present (PG 7.4.3), I'm thinking the only approach may be
to get the name of the table (TG_RELNAME) and then go and look up it's
structure in pg_attribute or something (the same as shown by
information_schema.columns). Not sure how to do that either yet, and a
better solution would be nifty.
PL/TCL does seem to provide that extra bit of info to functions/triggers
that I need, whereas PL/pgSQL doesn't. I'd prefer not to have to load
further PL's into the database, but it's worth looking at anyway.
