Trying to understand how I can get Pg 8.2 to match 'martín' when I search for 'martin', and going through the documentation, specially http://www.postgresql.org/docs/8.2/static/locale.html http://www.postgresql.org/docs/8.1/static/functions-matching.html Here is a transcript of my commandline - I suspect I am quite close, but something is missing. Hints _really_ appreciated! # do I have a Spanish locale on this box? locale -a # no I don't - let's make one sudo locale-gen es_AR.utf8 # check that I have it locale -a ... sudo pg_createcluster --locale=es_AR.utf8 8.2 arg sudo pg_ctlcluster 8.2 arg start sudo -u postgres createdb --cluster 8.2/arg testing sudo -u postgres psql --cluster 8.2/arg testing # in psql... =# create table test (value text); CREATE TABLE =# insert into test values ('martín'); INSERT 0 1 # this is apparently the right way to # select base character based on the "equivalence class" # as defined in the LC_CTYPE =# select * from test where value ~ 'mart[=i=]n'; value ------- (0 rows) # grumble - double check =# SHOW LC_CTYPE; lc_ctype ------------ es_AR.utf8 Any hints in general? - How can I read the LC_CTYPE definition? IOWs locale-gen has created a binary blob in /usr/lib/locale/es_AR.utf8/LC_CTYPE but I sure there is a human-readable definition somewhere... - Is that the correct syntax? - Pg bug? I doubt many people are counting on this behaviour... as it seems to be widely announced to be brittle and slow. cheers, m -- ----------------------------------------------------------------------- Martin @ Catalyst .Net .NZ Ltd, PO Box 11-053, Manners St, Wellington WEB: http://catalyst.net.nz/ PHYS: Level 2, 150-154 Willis St OFFICE: +64(4)916-7224 UK: 0845 868 5733 ext 7224 MOB: +64(21)364-017 Make things as simple as possible, but no simpler - Einstein -----------------------------------------------------------------------
