Setup a sync, make sure "ping" is off (so it does not automatically update the slave on master activity), and then you can manually "kick" the sync whenever you want to update the slave. (Apologies for all the Bucardo terminology) Some possible drawbacks: * Bucardo can only replicate tables incrementally that have a primary key or a unique index. If the table has neither, it can only copy the entire table each time. * If you go a long time between slave updates, the table that holds queued changes on the master will get quite large, and the update will, naturally, take longer. Both are not too much of a concern, but if you have tables that change nearly all of their data between updates, you may want to switch to a different method and copy the entire table instead. - -- Greg Sabino Mullane greg@xxxxxxxxxxxx End Point Corporation http://www.endpoint.com/ PGP Key: 0x14964AC8 201007191737 http://biglumber.com/x/web?pk=2529DF6AB8F79407E94445B4BC9B906714964AC8 -----BEGIN PGP SIGNATURE----- iEYEAREDAAYFAkxExdYACgkQvJuQZxSWSshTMgCgmNBMil740wtFMtAut083GKET dv8AoOqhtNLy5orQGOJK4eZrWJzbJxG9 =iUBd -----END PGP SIGNATURE----- -- Sent via pgsql-admin mailing list (pgsql-admin@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-admin
