Hi there, this is my first post.
I have a PostgreSQL 8.3.6, compiled by Visual C++ build 1400 running on
Windows with virtual machine, 2 GB ram, and configured the postgresql.conf
file to log statements duration >= 500 ms.
And I have this query/log entry:
2011-01-03 23:06:29 BRT LOG: duration: 2843.000 ms statement: SELECT
DESCRICAO FROM CURSO WHERE CODCURSO = 2
My question is, this same query executes many times a day and many times
fast/normal, but why in some cases its run slowly? Especialy because the
"CODCURSO" column is PK and this table has only 3 registers (tiny table).
Thank you in advance!
Fernando
