"traditional" behavior, so the change should be transparent. Use the
command "\pset pager always" to turn it on. Anything else does the
normal toggle between "on" and "off"

precision for float4, float8, and geometric types. Set it in pg_dump
so that float data can be dumped/reloaded exactly (at least on platforms
where the float I/O support is properly implemented). Initial patch by
Pedro Ferreira, some additional work by Tom Lane.
the documentation and behavior of "pg_result $res -oid" when $res is not
from an INSERT. The documentation says it should return an empty
string, but in fact it returns 0. I think it used to return an empty
string around PostgreSQL-7.1.3 when PQoidStatus() was used, but now it
uses PQoidValue() which returns InvalidOid, 0 in this case.
Assuming the current behavior is desired, here is a patch to the
documentation doc/src/sgml/libpgtcl.sgml to match what really happens:
