These changes assume that the varchar and xml data types are represented
the same as text.  (I did not, however, accept the portions of the proposed
patch that wanted to assume bytea is the same as text --- tgl.)

any hardcoding of those options. Along the way, reorder the expression used to
calculate RELSEG_SIZE to make it slightly clearer. For now wal_segsize is only
allowed to have a value of 1 on Windows - we can relax that when we get full
large file support in the backend.

let XLOG_BLCKSZ and XLOG_SEG_SIZE be set via configure.  Per a proposal by
Mark Wong, though I thought it better to call the switches after "wal" rather
than "xlog".

This has been the only documented and encouraged syntax for a long time, and
with extension facilities such as aliases being proposed, it is a good time to
clean up the legacy syntax a bit.

support for a nonsegmented mode from md.c.  Per recent discussions, there
doesn't seem to be much value in a "never segment" option as opposed to
segmenting with a suitably large segment size.  So instead provide a
configure-time switch to set the desired segment size in units of gigabytes.
While at it, expose a configure switch for BLCKSZ as well.

so there seems no reason not to include it.  Per a recent gripe.

it vary with BLCKSZ as before.  This agrees with what the documentation says,
and avoids a regression test problem when BLCKSZ is larger than default.
Per recent discussion.

a user-supplied TID is out of range for the relation.  This is needed to
preserve compatibility with our pre-8.3 behavior, and it is sensible anyway
since if the query were implemented by brute force rather than optimized
into a TidScan, the behavior for a non-existent TID would be zero rows out,
never an error.  Per gripe from Gurjeet Singh.

makeFloatConst, and avoid "manual" construction of A_Const nodes in grammar
productions, in favor of using makeXXXConst subroutines.

The capability for changing language owners is new in 8.3, so that's how
far back this needs to be backpatched.

flags by separate AT_SetNotNull subcommands.  That was always ugly and
inefficient, and it's now clear that it was merely a partial workaround
for the bug just identified in ATExecAddColumn.  This is just code
beautification not a bug fix, so no back-patch.

checked to see if it's been initialized to all non-nulls.  The implicit NOT
NULL constraint was not being checked during the ALTER (in fact, not even if
there was an explicit NOT NULL too), because ATExecAddColumn neglected to
set the flag needed to make the test happen.  This has been broken since
the capability was first added, in 8.0.
