The patch doesn't seem to apply cleanly on head (I have a problem with
oracle_compat.c). I tested it though with latin1 encoding.
The LIKE case is better:
cityvox_latin1=# SELECT e.numeve FROM evenement e WHERE e.libgeseve
LIKE '%hocus pocus%';numeve
--------
(0 rows)
Time: 98.995 ms
-> it seems to be as fast as 8.2 was, now.
The ILIKE case seems to go into an infinite loop: postmaster takes
100% of CPU and the query never finishes.
