Re: underscore pattern in a query doens't work

Thanks Tom, for your suggestions.
We started the cluster up with this command:
./initdb -D /usr/local/postgre/data -E UTF8 -U sir

The rest of the variables related to encoding (locale) are:
lc_collate=C
lc_ctype=C
lc_messages=C
lc_monetary=C
lc_numeric=C
lc_time=C

Could you tell me which more info could I give you?

I suspect what you have here is an encoding problem.  That is, probably
the "í" is represented as a multi-byte character (most likely UTF8)
but the server thinks it's working with a single-byte encoding so that
any one character should be only one byte.

You didn't say what your encoding setup is, so it's hard to do more
than speculate.

You do realize this is about 3 years out of date?  The 8.4 series is up
to release 8.4.13, and a lot of those updates contained fixes for
serious bugs.
