[SR-Users] DB ERROR using presence status persistence

[Nuno Reis]

Hi guys.

I've setup presence management in kamailio and i'm currently persisting the
presence info in a postgres DB.
I'm having a recurring issue on DB key violations, here's a log error
output on that:

I've read the module documentation, but there isn't much documentation on
it and i'm basically guessing and trying here.
Can someone tell me what am i doing wrong or maybe what should a try to be
able to persist the presence status in a postgres database.
I know that i could use in memory persistence or other  type of DB, but i
really want to know if i can use a normal postgres DB for presence
persistence and what could be used to avoid key violations.

Looking forward to hear from you.
Best Regards,
