postgresql.conf.
- shared_buffers = 32000kB => 32MB
- temp_buffers = 8000kB => 8MB
- wal_buffers = 8 => 64kB
The code of initdb was a bit modified to write MB-unit values.
Values greater than 8000kB are rounded out to MB.
GUC_UNIT_XBLOCKS is added for wal_buffers. It is like GUC_UNIT_BLOCKS,
but uses XLOG_BLCKSZ instead of BLCKSZ.
Also, I cleaned up the test of GUC_UNIT_* flags in preparation to
add more unit flags in less bits.

which turns out to be a dominant part of the runtime in scenarios
involving lots of parse-time warnings (such as Stephen Frost's example
of an INSERT with a lot of backslash-containing strings). There's not
a whole lot we can do about the character-at-a-time scanning, but we
can at least avoid traversing the query twice.

severity. This is to ensure the user can cancel a query that's spitting
out lots of notice/warning messages, even if they're coming from a loop
that doesn't otherwise contain a CHECK_FOR_INTERRUPTS. Per gripe from
Stephen Frost.

present; intervening positions are filled with nulls. This behavior
is required by SQL99 but was not implementable before 8.2 due to lack
of support for nulls in arrays. I have only made it work for the
one-dimensional case, which is all that SQL99 requires. It seems quite
complex to get it right in higher dimensions, and since we never allowed
extension at all in higher dimensions, I think that must count as a
future feature addition not a bug fix.

NULL. Noted by Teodor.

the SQL spec, viz IS NULL is true if all the row's fields are null, IS NOT
NULL is true if all the row's fields are not null. The former coding got
this right for a limited number of cases with IS NULL (ie, those where it
could disassemble a ROW constructor at parse time), but was entirely wrong
for IS NOT NULL. Per report from Teodor.
I desisted from changing the behavior for arrays, since on closer inspection
it's not clear that there's any support for that in the SQL spec. This
probably needs more consideration.

undertaken sometime, but not during beta.) This commit also fixes dynahash.c
to correctly truncate overlength string keys for hashtables, so that its
callers don't have to anymore.
