[HACKERS] create index regression fail
Hi, In current HEAD, create index regression is failing (at least here). Is anyone else seeing this? Attached regression.diffs the query where the regression fails is: SELECT count(*) FROM dupindexcols WHERE f1 'LX' and id 1000 and f1 ~~ 'YX'; my first theory was that it was because some locale because mine is es_EC.UTF-8 but the content of the table doesn't justify that, my second theory was that it was because the index-only scan it's does but turning off indexonly scan didn't give a different answer this test case was added in commit e2c2c2e8b1df7dfdb01e7e6f6191a569ce3c3195 to Improve planner's handling of duplicated index column expressions, so this commit broke something or the count is wrong in the expected result -- Jaime Casanova www.2ndQuadrant.com Professional PostgreSQL: Soporte 24x7 y capacitación regression.diffs Description: Binary data -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers

In ec_EC locale on my machine, the test accepts these rows that are not accepted in C locale: 223 | LLKAAA 738 | LLEAAA I'll change the lower bound to 'MA' and see if that's any more portable. 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

Yeah, some of these are pretty recent developments by the real academia de la lengua, I guess glibc hasn't gotten word about it 100% yet. On the other hand I wonder if es_EC is different from other spanish locales for some reason ... -- Álvaro Herrera alvhe...@commandprompt.com The PostgreSQL Company - Command Prompt, Inc.
