Why dont you try to make 'username' part of your query.
While auditing updates and inserts, the username can be some how made
a part of the tuple being inserted. Just a thought!

Hi ,
Is there any way to set a variable from a web application (using dbi/perl ,
libpq etc),
and access the same variable from a C trigger inside a transaction ?
the %_SHARED hash available in plperl provides only session level isolation
and
does not suit the requirement.
Original problem:
we want to setup table auditing using table_log or audittrail projects.
the triggers used in these systems uses the current database user
to log to the audit tables..
In our webapps, we use the same username to connect to the database
for all kind of updates. Hence we are not able to makeout whoo modified
what . However at application level we have different "userid" for different
users of the system. we want to somehow pass this "userid" to the databasee
server and accesss it from the triggers that implement the audit functions.
we thought of using a table of single row and single column to store
the userid but we are concerned over the performance due to locking
issues.
