Error handling in PL/PgSQL (without execution termination)

I am searching for the resource that explains how to handle SQL
related exceptions in PL/PgSQL without letting the function's
execution terminate.
I would like to use his to address possible UNIQUE constraint
violation (and resulting exception) attributed to multiple clients
concurrently populating the given table.

Allan.
