PSQL locks records in the table... - Mailing list pgsql-novice

Hi,
I have a very annoying problem :
My Psql locks a few records on a few tables.

Why?  I don't know, but it is very stressful for the user of the
Access-frontend.

Can i unlock this easy?  Can I do something for not having this in the
future?

Thanks in advance!!!
Joepie.
