- Variables that are out of scope, were not removed all the time.
- Make a varchar NULL set everything to 0 when not using indicators.
- Synced parser.
specified in just one place and adhered to exactly, rather than just more
or less. A side effect is to increase PGSTAT_ACTIVITY_SIZE (maximum
reported query length) from 256 to nearly 1000.
aggregates, conversions, functions, operators, operator classes,
schemas, types, and tablespaces. Fold the existing implementations
of alter domain owner and alter database owner in with these.

This eliminates the assumption that a serial column's sequence will
have the same name on reload that it was given in the original database.

creation of user-defined tablespaces with names starting with 'pg_', as
per suggestion of Chris K-L. Also install admin-guide tablespace
documentation from Gavin.
to reference the spinlock variable, and specify "memory" as a clobber
operand to be sure gcc does not try to keep shared-memory values in
registers across a spinlock acquisition. Also tighten the S/390 asm
sequence, which was apparently written with only minimal study of the
gcc asm documentation. I have personally tested i386, ia64, ppc, hppa,
and s390 variants --- there is some small chance that I broke the others,
but I doubt it.
should recognize 'foo.*' when the star appears in A_Indirection, not only
in ColumnRef. This allows 'SELECT something.*' to do what the user
expects when the something is an expression yielding a row.
I kept the same abbreviated letter -D, in hopes of maintaining some
modicum of backwards compatibility (though it's doubtful whether anyone
is really using scripts that invoke createdb -D ...)
There are various things left to do: contrib dbsize and oid2name modules
need work, and so does the documentation. Also someone should think about
COMMENT ON TABLESPACE and maybe RENAME TABLESPACE. Also initlocation is
dead, it just doesn't know it yet.

eliminating the former hard-wired convention about their names. Allow
pg_cast entries to represent both type coercion and length coercion in
a single step --- this is represented by a function that takes an
extra typmod argument, just like a length coercion function. This
nicely merges the type and length coercion mechanisms into something
at least a little cleaner than we had before. Make use of the single-
coercion-step behavior to fix integer-to-bit coercion so that coercing
to bit(n) yields the rightmost n bits of the integer instead of the
leftmost n bits. This should fix recurrent complaints about the odd
behavior of this coercion. Clean up the documentation of the bit string
functions, and try to put it where people might actually find it.
Also, get rid of the unreliable heuristics in ruleutils.c about whether
to display nested coercion steps; instead require parse_coerce.c to
label them properly in the first place.
begin the shutdown checkpoint; there isn't anything left for them to do,
so we may as well ensure that they shut down sooner rather than later.
Per discussion.
cidr type bit, the same as network_eq does. This is needed for hash joins
and hash aggregation to work correctly on these types. Per bug report
from Michael Fuhr, 2004-04-13.
Also, improve hash function for int8 as suggested by Greg Stark.
not holding the buffer's cntx_lock or io_in_progress_lock. A recent
report from Litao Wu makes me wonder whether it is ever possible for
us to drop a buffer and forget to release its cntx_lock. The Assert
does not fire in the regression tests, but that proves little ...
