This is the wrong list for this question. I recommend you read up on indexes and make some attempts at solving the problem yourself. If you can't reach the level of performance you expect, try to present a more specific question to pgsql-novice (if it is about how indexes in PostgreSQL work in general) or pgsql-performance (if you can't understand why a particular attempt to solve the problem is not performing as well as you think it should. http://www.postgresql.org/docs/current/static/sql-createindex.html http://www.postgresql.org/docs/current/static/indexes.html http://wiki.postgresql.org/wiki/SlowQueryQuestions -Kevin

There some specific recommendations that depend what you needindexes for, but first ensure you know the basics for creating an index. Note that knowing how to RTFM is an importantskill for developers...<br /><br /> I know the package that comes with Fedora includes documentation, so you mighthave documentation already on your machine.<br /><br /> Also it is best to say what operating system and what versionof Postgres you are using.<br /><br /><br /> Cheers,<br /> Gavin<br /><br />
