I don't use the Postgres ODBC driver for real and I only hang about on
this list as I look after Perl DBD::ODBC.
In some ODBC drivers output parameters passed to procedures are only
available after SQLMoreResults returns negatively i.e., your procedure
must finish before the output bound parameters are available and
certainly in MS SQL Server unless nocount is on, any
insert/update/delete requires SQLMoreResults to be called repeatedly to
walk through the results in the procedure.
I've no idea if this is the reason for your first problem but thought it
worth mentioning.
