Nop Just I know how it's developed.

As far as I know, the wildfly's jdbc pool. No really I don't know what are
doing. I suspect that problem is that in DAO's not are closing the sessions
or not beginning transactions properly. I going to ask them send me the
logfile or I'll could verify the pool behavior.

Sorry, it's not like that, just was a comment, The problem I have is with a
specific application.

Melvin , Thanks for the scripts! I owe one!
I have another question, I've was reading about the lock_timeout, Somehow
this parameter will help or could affect all the behaviour?
Thanks!

- lock_timeout (integer)
Abort any statement that waits longer than the specified number of milliseconds while attempting to acquire a lock on a table, index, row, or other database object. The time limit applies separately to each lock acquisition attempt. The limit applies both to explicit locking requests (such as LOCK TABLE, or SELECT FOR UPDATE without NOWAIT) and to implicitly-acquired locks. If log_min_error_statement is set to ERROR or lower, the statement that timed out will be logged. A value of zero (the default) turns this off.
Unlike statement_timeout, this timeout can only occur while waiting for locks. Note that if statement_timeout is nonzero, it is rather pointless to set lock_timeout to the same or larger value, since the statement timeout would always trigger first.
Setting lock_timeout in postgresql.conf is not recommended because it would affect all sessions.
