This is the first run of the Perl-based pgindent script. Also update
pgindent instructions.

We had two copies of this function in the backend and libpq, which was
already pretty bogus, but it turns out that we need it in some other
programs that don't use libpq (such as pg_test_fsync). So put it where
it probably should have been all along. The signal-mask-initialization
support in src/backend/libpq/pqsignal.c stays where it is, though, since
we only need that in the backend.

This includes backend "COPY TO/FROM PROGRAM '...'" syntax, and corresponding
psql \copy syntax. Like with reading/writing files, the backend version is
superuser-only, and in the psql version, the program is run in the client.
In the passing, the psql \copy STDIN/STDOUT syntax is subtly changed: if you
the stdin/stdout is quoted, it's now interpreted as a filename. For example,
"\copy foo from 'stdin'" now reads from a file called 'stdin', not from
standard input. Before this, there was no way to specify a filename called
stdin, stdout, pstdin or pstdout.
This creates a new function in pgport, wait_result_to_str(), which can
be used to convert the exit status of a process, as returned by wait(3),
to a human-readable string.

Fully update git head, and update back branches in ./COPYRIGHT and
legal.sgml files.

We had a number of variants on the theme of "malloc or die", with the
majority named like "pg_malloc", but by no means all. Standardize on the
names pg_malloc, pg_malloc0, pg_realloc, pg_strdup. Get rid of pg_calloc
entirely in favor of using pg_malloc0.
This is an essentially cosmetic change, so no back-patch. (I did find
a couple of places where psql and pg_dump were using plain malloc or
strdup instead of the pg_ versions, but they don't look significant
enough to bother back-patching.)

commit-fest.

This enables a bunch of features, notably ON_ERROR_ROLLBACK. It also
makes COPY failure (either in the server or psql) as a whole behave more
sanely in psql.
Additionally, having more commands in the same command line as COPY
works better (though since psql splits lines at semicolons, this doesn't
matter much unless you're using -c).
Also tighten a couple of switches on PQresultStatus() to add
PGRES_COPY_BOTH support and stop assuming that unknown statuses received
are errors; have those print diagnostics where warranted.

handleCopyIn incremented pset.lineno for each line of COPY data read from
a file. This is correct when reading from the current script file (i.e.,
we are doing COPY FROM STDIN followed by in-line data), but it's wrong if
the data is coming from some other file. Per bug #6083 from Steve Haslam.
Back-patch to all supported versions.

trying to parse COPY options exactly in psql's \copy support. Instead,
just send the options as-is and let the backend sort it out.

when we reach the post-COPY "pump it dry" error recovery code that was added
2006-11-24. Per a report from Neil Best, there is at least one code path
in which this occurs, leading to an infinite loop in code that's supposed
to be making it more robust not less so. A reasonable response seems to be
to call PQputCopyEnd() again, so let's try that.
Back-patch to all versions that contain the cleanup loop.

QUOTE * as a variety of FORCE QUOTE, and update psql documentation to include
the option. (The actual psql code doesn't seem to need any changes.)

if there are any Windows configurations where port/win32.h fails to
provide the macro, it should be fixed in the latter file not here.

back-stamped for this.

(in particular, causing the ReadyForQuery message to be eaten) before
returning from do_copy. The only known consequence of failing to do so is
that get_prompt might show a wrong result for the %x transaction status
escape, as reported by Bernd Helmle; but it's possible there are other issues.
Back-patch as far as 7.4, the oldest version supporting %x.

existing for backend GUC variables, and use this to eliminate repeated
fetching/parsing of psql variables in psql's inner loops. In a trivial
test with lots of 'select 1;' commands, psql's CPU time went down almost
10%, although of course the effect on total elapsed time was much less.
Per discussion about how to ensure the upcoming FETCH_COUNT patch doesn't
cost any performance when not being used.

places --- that risks corrupting data structures, losing sync with the
backend, etc. We now longjmp only from calls to readline, fgets, and
fread, which we assume are coded to protect themselves against interrupts
at undesirable times. This requires adding explicit tests for
cancel_pressed in long-running loops, but on the whole it's far cleaner.

and there's only one place that's a kluge, ie, appendStringLiteralConn.
Note that pg_dump itself doesn't use appendStringLiteralConn, so its
behavior is not affected; only the other utility programs care.

o turns off escape_string_warning in pg_dumpall.c
o optionally use E'' for \password (undocumented option?)
o honor standard_conforming-strings for \copy (but not
support literal E'' strings)
o optionally use E'' for \d commands
o turn off escape_string_warning for createdb, createuser,

conversion of basic ASCII letters. Remove all uses of strcasecmp and
strncasecmp in favor of new functions pg_strcasecmp and pg_strncasecmp;
remove most but not all direct uses of toupper and tolower in favor of
pg_toupper and pg_tolower. These functions use the same notions of
case folding already developed for identifier case conversion. I left
the straight locale-based folding in place for situations where we are
just manipulating user data and not trying to match it to built-in
strings --- for example, the SQL upper() function is still locale
dependent. Perhaps this will prove not to be what's wanted, but at
the moment we can initdb and pass regression tests in Turkish locale.
