Thanks Rob,
no it's not a problem with the index. It's a problem with the use of
CURRENT_USER in the WHERE
I submitted a new post on this matter with a test case.
Kind regards

9.3 plan
-> Index Scan using client_session_user_id_idx on client_session
Looks like a collation issue given the difference in compilers used.
In the 9.3 plan the index is used.
Maybe try a reindex of the table.
HTH,
