Thread: pgsql: Check return value of strdup() in libpq connection option parsin

Check return value of strdup() in libpq connection option parsing.

connecting to a different database than intended, but some would lead to
an outright segfault.

Alex Shulgin and me. Backpatch to all supported versions.
