Hi I am from a MSSQL background and am trying to understand something about statistics in PostgreSQL. Question 1: In MSSQL, if you create an index (and you are using MSSQL's default settings) the Server will automatically create appropriate statistics for you. Does this happen in PostgreSQL? Or should I explicitly create statistics for every one of my indexes? Question 2: I believe ANALYZE keeps indexes and statistics up to date. How often should this be run (assume that my DB has 200,000 new records daily)? Thanks in advance Craig ---------------------------(end of broadcast)--------------------------- TIP 3: if posting/reading through Usenet, please send an appropriate subscribe-nomail command to majordomo@xxxxxxxxxxxxxx so that your message can get through to the mailing list cleanly
