No, pgsql-odbc is the right forum.

Is the version 7.01.0006 ?

Is the comparison for the < 8k data ?
Is it as fast as 6.4/7.0 except concurrent write ?

Please download the latest driver 7.01.0006.
Other drivers couldn't handle text fields > 8k.

Are you checking the 'Text as LongVarChar' driver option ?

Done that now...

Yes.

It doesn't look like an ODBC issue now...

I have tried all ODBC drivers 6.4, 7.0 and 7.1
with less than 8kb fields and they all seem to
have this same problem with timeout.

To me this seems like a 7.1 database issue
we didn't seem to have with 6.4 and 7.0

Not sure what the timeout is, but I assume
a lock condition.

Without the large text attachment.

Not sure... lookups/queries are great (indexed and
vacuum-analyzed) I think the write is slow... (and
unsuccessful) because of a time-out.
