[Gambas-user] Postgres - obscure problem with oids

I have a table ("tableext") which is an "extension" to the system
pg_catalog pg_class table. tableext relates to the pg_class on 1:1 basis
via the pg_class OID. Inn the tableext class that oid (called "tname")
a) is the primary key and
b) has a datatype of "regclass", IOW the table displays the OID as a
table name instead of an OID.
That is all standard stuff in postgres whwn dealing with the catalog.
Here's my problem. In Gambas I am trying to update a row in this
I can get an updateable result using
hBuffer = $srcConn.Edit("dd.tableext", "tname = &1::regclass",
In other words I am forcing the integer OID from the tname. That's fine
and I get an updatable cursor.
But when I get to the hBuffer.Update point Gambas is trying to use the
string tname and I cant see how to tell it to pass the ::regclass back
to the postgres server, A sample db.debug output of the query it is
trying to execute is:
SET "cat" = $$LOOKUP$$,
"facade" = $$Reference$$,
"is audited" = FALSE,
"strength" = $$STRONG$$,
"aspect" = $$Reference$$,
"comments" = NULL,
"disposition" = NULL,
"centity" = NULL,
"boclass" = $$BPGroups$$
WHERE "tname" = $$bpgroups$$
I need that last line to be
WHERE "tname" = $$bpgroups$$::regclass.
Any clues (apart from writing specific update queries which is too
onerous for the number of thesse I have to do).
