My function (on pid 20125) was running, pid 25743 requested an exclusive lock and is waiting, and all others were waiting for this one.

Hi all,
I had a big function (the same one mentioned before) which is locking a table, where it doesn't use the table for updates, just selects. (PostgreSQL 8.2)
My pg_locks had:
sgn=# SELECT * FROM pg_locks WHERE relation = 1706665;
locktype | database | relation | page | tuple | transactionid | classid | objid | objsubid | transaction | pid | mode | granted
----------+----------+----------+------+-------+---------------+---------+-------+----------+-------------+-------+---------------------+---------
relation | 1705022 | 1706665 | | | | | | | 160710046 | 20125 | AccessShareLock | t
relation | 1705022 | 1706665 | | | | | | | 160721896 | 24198 | AccessShareLock | f
relation | 1705022 | 1706665 | | | | | | | 160721876 | 25744 | AccessShareLock | f
relation | 1705022 | 1706665 | | | | | | | 160721874 | 25743 | AccessExclusiveLock | f
(4 registros)
What could be wrong? How could I get an access share lock only using select? Any way to avoid it? My fuction runs for 3 minutes and every developer is trying to kill me, because they are waiting for their results.
Regards,
