Thanks Merin.
It does, and that's probably what I'll do. Your solution isn't great
either, because it requires extra function to be run on the postgresql
side. Me no likeey that ;)
When you say parameterized - it allows you to prepare queries - which
I do in 80% of select/insert/update cases, apart from some older code
that no one wants to touch.
But the time came for me to act on it, and try to put us forward using
9.1 instead of old rusty 8.3 (which is still better then 8.1 they used
before I started working here).
m_connection.prepare("INSERT INTO foo(x) VALUES($1)") ("bytea",
pqxx::prepare::treat_binary);
Gotta try that one with both boys ;)
Btw, I hope 9.1.1 is out soon, gotta package some version for tests.
We used floating point timestamps, and I gotta repackage centos rpms
with that config option - otherwise it's pg_dump and restore of gigs
of data....
