Yes, no problem with any of those kind of facilities > - Can we create tempory tables in standby? No, but this is for two reasons * CREATE TEMPORARY TABLE actually writes to catalog tables. It doesn't need to do that, so allowing this would require some medium-heavy lifting of the way temp tables work. A preliminary design was agreed in July 2008. I believe it would be a popular feature, since about 40-50% of people ask for this. * CREATE TEMP TABLE is currently considered to be disallowed during read only transactions. That might be able to change if the underlying physical operation were write-free. -- Simon Riggs www.2ndQuadrant.com -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
