theoretically vary depending on what the compile-time locale setting is.
Hence, force it to see LC_CTYPE=C to ensure consistent build results.
(It's likely that this makes no difference in practice, since our
specification for "identifier" surely includes both ends of any possible
uppercase/lowercase pair anyway.  But it should silence warnings about
ambiguous character classes that are reported by some buildfarm members.)

sanely if the loop value overflows int32 on the way to the end value.
Avoid useless computation of "SELECT 1" when BY is omitted.  Avoid some
type-punning between Datum and int4 that dates from the original coding.

of variable substitution and plan caching behavior in dedicated sections.
(A lot of this material existed already, but was scattered in various places
in the chapter.)  Reorganize material a little bit, mostly to try to avoid
diving into deep details in the first introductory sections.  Document some
fine points that had escaped treatment before, notably the ability to qualify
plpgsql variable names with block labels.  Some minor wordsmithing here and
there.

necessary for correctness, but less warnings are always good.

someone's first effort at backend coding.

define pg_dlsym() as returning a PGFunction pointer, not just any

on platforms that aren't careful by inserting explicit casts at the
two call sites that didn't have a cast already.  Per Stefan.

This fixes a very hard to track down heap corruption on windows

Per suggestion from Alvaro.

* use elog not ereport for debug
* fix debug levels for some output
* properly check for memory allocation errors in a couple of missed places

building from a distribution tarball does not.

Documentation still being written, will be committed later.

literally, whether quoted or not.  Since we allow $ as a character within
identifiers, this behavior is useful, whereas the previous behavior of
treating it as the regexp ending anchor was nearly useless given that the
pattern is automatically anchored anyway.  This affects the arguments of
psql's \d commands as well as pg_dump's -n and -t switches.  Per discussion.
