Well, it ignores built-in functions. Naming the view that way seems like good future-proofing to me --- maybe someday we'll think of a sufficiently low-overhead way to offer stats for system functions too. regards, tom lane -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers

Uh, not really; the optimizer stuff is usually quite vague and Tom might end update removing it once he goes over the release note anyway (he has in the past). I documented it because it is a user-visible change, I think, becuase it might show up in EXPLAIN. -- Bruce Momjian br...@momjian.ushttp://momjian.us EnterpriseDB http://enterprisedb.com + If your life is a hard drive, Christ can be your backup. + -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers

[HACKERS] 8.4 release notes proof reading 1/2
Hi, Just to warn people that I'm making a comprehensive proof reading of the release notes. Here are the first comments: - This was available previously via a configure --enable-integer-datetimes (Neil Conway) - I don't think we need Neil's name in the details - New semi- and ansi-joins (Tom) - s/ansi/anti/ - While semi-joins merely replace existing IN joins, anti-joins are a new capability for NOT IN and NOT EXIST clauses (Tom) This improves optimization possibilities. - remove the (Tom), s/EXIST/EXISTS/ - IN and EXISTs now provide similar performance for equivalent clauses. - s/EXISTs/EXISTS/ - A new constraint_exclusion setting, partition, which matches this behavior. - this sentence is weird - Move that server statistics file into the subdirectory pg_stat_tmp - s/that/the/ ? I think this item can be grouped with the following one Allow the location of the new pg_stat_tmp to be configured via the stats_temp_directory setting I'll post the other part in a few hours. -- Guillaume -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
Re: [HACKERS] 8.4 release notes proof reading 1/2
Bruce, Here is the second set of comments: - pg_hba.conf: it seems to me the format has changed which may break existing pg_hba.conf (it broke the default one of the RPM packaging). We should make it very visible as the format hasn't changed for a while. I suppose we'll put it at the top but I just don't want us to forget it so I mention it here. - Allow recovery.conf boolean variables to take the same range of string alues as postgresql.conf (Bruce) - s/alues/values/ - Add support for Unicode sting and identifier specifications using code points, e.g. U'd\0061t\+61' (Peter) - s/sting/string/ - Allow CREATE OR REPLACE VIEW to add columns to the _end_ of the view - formatting problem with the underscores? - Previously EXPLAIN VERBOSE output an internal representation of the query plan - s/output/outputs/ ? - Autovacuum options uses to be stored in a system table. - s/uses/used/ ? - Allows dumps to fail if unable to acquire shared table within the specified amount of time. - shared lock instead of shared table? - Add configure option --disable-float4-byval to use the old behavior. tgl Pass float8 and int8 by value in the server where possible (Zoltan Boszormenyi) - tgl + there's a carriage return missing (and a bullet) - Add -M (query mode) to /contrib/pgbench (ITAGAKI Takahiro) -Itagaki san's name inconsistent with other mentions of his name I can provide a patch for all this if needed. I thought you'd prefer validate the changes. Really nice work and really interesting reading.

The existing wording seems correct. I think Bruce's phrasing was in the past tense. It's a bit weird because the verb form of output is a relatively recent invention and the past tense isn't well settled. Dictionaries list both outputted and output as past tense forms. Personally I think Bruce's output sounds better than the alternative outputted. Perhaps had output would be clearer? -- greg -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
