It currently is not generic to PostgreSQL, but you can do that with the dblink extension/functions. -- Melvin Davidson I reserve the right to fantasize. Whether or not you wish to share my fantasy is entirely up to you. <http://us.i1.yimg.com/us.yimg.com/i/mesg/tsmileys2/01.gif> I know about dblink =) The question was – is there any caveats to not allow xross db access. Maybe some security considerations prevent to implement it. We all know that PG = one process rules multiple DBs why not to allow direct access to another DB. We have one transaction counter and so on where is the problems if any? -- Alex Ignatov Postgres Professional: <http://www.postgrespro.com> http://www.postgrespro.com The Russian Postgres Company
