pgsql-server: Allow plpgsql to pass composite-type arguments (ie, - Mailing list pgsql-committers

Log Message:
-----------
Allow plpgsql to pass composite-type arguments (ie, whole-row variables)
into SQL expressions.  At present this only works usefully for variables
of named rowtypes, not RECORD variables, since the SQL parser can't infer
anything about datatypes from a RECORD Param.  Still, it's a step forward.
