has an alias SERIAL4 and a sister SERIAL8. SERIAL8 is just the same
except the created column is type int8 not int4.
initdb forced. Note this also breaks any chance of pg_upgrade from 7.1,
unless we hack up pg_upgrade to drop and recreate sequences. (Which is
not out of the question, but I don't wanna do it.)
Allow pg_shadow to be MD5 encrypted.
Add ENCRYPTED/UNENCRYPTED option to CREATE/ALTER user.
Add password_encryption postgresql.conf option.
Update wire protocol version to 2.1.
for speed reasons; its result type also changes to int8. avg() on these
datatypes now accumulates the running sum in int8 for speed; but we still
deliver the final result as numeric, so that fractional accuracy is
preserved.
count() now counts and returns in int8, not int4. I am a little nervous
about this possibly breaking users' code, but there didn't seem to be
a strong sentiment for avoiding the problem. If we get complaints during
beta, we can change count back to int4 and add a "count8" aggregate.
For that matter, users can do it for themselves with a simple CREATE
AGGREGATE command; the int4inc function is still present, so no C hacking
is needed.
Also added max() and min() aggregates for OID that do proper unsigned
comparison, instead of piggybacking on int4 aggregates.
initdb forced.
syntax for language names (instead of 'string').
createlang now handles the case where a second language uses the same call
handler as an already installed language (e.g., plperl/plperlu).
droplang now handles the reverse case, i.e., dropping a language where
the call handler is still used by another language. Moreover, droplang
can now be used to drop any user-defined language, not just the supplied
ones.
Don't hardcode the maximum accepted server version, use PG_VERSION instead.
Install a notice processor so notices are handled like error messages.
Word smithing.
default, but OIDS are removed from many system catalogs that don't need them.
Some interesting side effects: TOAST pointers are 20 bytes not 32 now;
pg_description has a three-column key instead of one.
Bugs fixed in passing: BINARY cursors work again; pg_class.relhaspkey
has some usefulness; pg_dump dumps comments on indexes, rules, and
triggers in a valid order.
initdb forced.
clauses are equal(), before trying to match them up using btree opclass
inference rules. This allows it to recognize many simple cases involving
non-btree operations, for example 'x IS NULL'. Clean up code a little.
Sorry I don't have the original around to make a quick diff, but its a very small change... I think this should be in the next release, there's no reason not to have it.
its a function with no expected arguments, so you can use it like:
spi_exec "INSERT INTO mytable(columns...) VALUES(values..)"
set oid [spi_lastoid]
spi_exec "SELECT mytable_id from mytable WHERE oid=$oid"
It just didn't make sense for me to use plpgsql and pltcl, or just screw
them both and use SPI from C.
