Обсуждение: find open transactions/locks in 7.2?

[select version() --> PostgreSQL 7.2 on i686-pc-linux-gnu, compiled by GCC 3.0.4]

I'm getting hangups every day or so, I presume due to some open transaction
that insert/update/delete'ed on a table that is used by my main app without
a commit.

Is there some way (in 7.2!) to find who's locking what or who has
a transaction open?

AFAICT No.
There has been a thread on a similar topic
[HACKERS] Can pessimistic locking be emulated?
but it was all referring to 7.3.
Anyway, you might want to check.
