None of the replication solutions I have seen (at a resonable price)
allow me to limit the data being replicated by a specific field
(which I must do from a liability standpoint), so I'm rolling my own
replication using php as the scripting language. I've got the data
being transferred using inserts just fine, but I would suspect a
50-300% improvement in transfer speed if I could resort to COPY
instead (I'm inserting records in transactions of 500 rows each for
testing). One of the tables that I need to replicate is a
You would definatley see an improvement from using COPY but you could
have other problems. COPY does not happen within a transaction block
it just kind of shoves everything in there. You are going to be better
served in
the long run doing inserts.

Does anyone know how to execute a COPY from PHP?
I keep getting parse errors on all the data.
PHP 4.3.2
PostgreSQL 7.3.4
example:
CREATE table tmp(data text);
COPY tmp FROM STDIN;
