Silence uninitialized variable compiler warning in sepgsql

Browse Source 
At -Og optimization gcc warns that variable tclass may be used
uninitialized when relkind == RELKIND_INDEX. Actually that can't
happen due to an early return, but quiet the compiler by initializing
tclass to 0.

In passing, use uint16_t consistently for the declaration of tclass.

Complaint and initial patch by Mike Palmiotto. Editorializing by me.
Probably not worth backpatching given that it is cosmetic, so apply
to development head only.
