H Waldemar,

you can query the system-table "pg_class". The filed "relacl" holds the acl for the 
table.

The form is:
{RIGHT[,RIGHT]}

where RIGHT is in the form:
"[user]=[acl-for-user]"

acl-for-user is a combination of the following:
a - insert granted
r - select granted
w - update granted
R - rule granted

Sample Entry:
{"=","admin=arwR","simpleuser=r","updater=w"}

means:
PUBLIC: allowed nothing
admin: insert,select,update,rule
simpleuser: select
updater: update

Hope this works for you.

cu
Martin
