[GENERAL] cluster question
Hi I have setup a streaming replicating cluster, with a hot standby. Now I would like to change the RW to hot standby and change the hot standby to be the RW server. Is it just a matter of updating recover.conf file ? Alex

There's a considerable distance between "is the planner making appropriate use of indexes" and "I insist on an index-only scan". The reason you're not getting an index-only scan here is that that requires an index that includes every column referenced in the query, which you don't have. At minimum you'd need an index including all of autoinc, fileversion, and filename to do this query with an IOS. If you want it to be particularly efficient for this query then you'd need the index's column order to be (filename, autoinc, fileversion) --- putting filename means the entries satisfying WHERE will be clumped in the index, and putting autoinc second means that a backwards scan on that portion of the index is enough to produce the requested sort ordering without an explicit sort step. Whether it's worth maintaining an index this specialized depends on how much update traffic you have versus how often you want to do this particular query. Often it's not worth the extra disk space and update overhead to have such an index. In any case, I wouldn't worry about it until you have an actual performance problem. Trying to tell on toy data what the planner will do with production-sized data is usually a losing game. regards, tom lane -- Sent via pgsql-general mailing list (pgsql-general@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general

I will try to load up more dummy rows to overflow the work_mem and observe results. Sorry, my question was misleading. I do not want to use "set enable_seqscan = off" I want to be sure that when necessary (record count increases) relevant index(es) will be used. Obviously I still can't read query plan as I did not understand that operation is still in memory. Just for complete information,

Normally should reside in the data dir.

[GENERAL] Where is pg_hba.conf
Hi, I have a Mac with OSX 10.8 installed. It has Postgre 9.1. According to https://www.postgresql.org/docs/9.1/static/auth-pg-hba-conf.html and http://www.thegeekstuff.com/2014/02/enable-remote-postgresql-connection/?utm_source=tuicool I need to modify the pg_hba.conf file to get access to the DB remotely. However, I can't find this file anywhere on the system. I am able to connec to the server locally with psql. I can also connect to the server from the ODBC driver from my program. However doing a global search I can't find that file. Can someone please help?
