"WHERE CURRENT OF" Support in libpq Someday? - Mailing list pgsql-interfaces

I expect that ecpg supports cursors that include functionality
for constructs like:
 UPDATE EMPLOYEES SET MARRIED = 'T' WHERE CURRENT OF CURSOR_NAME;

but this support seems to be absent in libpq.

Is this being planned for a future release?  If so, which
one?

This is well supported feature by commercial databases (Oracle,
Sybase, Informix to name a few), but I just don't see any hint
of it coming to libpq.

TIA, Warren.
