temporary table; we can't support that because there's no way to clean up the
source backend's internal state if the eventual COMMIT PREPARED is done by
another backend.  This was checked correctly in 8.1 but I broke it in 8.2 :-(.

In the process expanded one test case,

of "VET" accordingly.  Per bug #3997 from Aaron Mizrachi.

"struct varlena" would be at least word-aligned.  Per buildfarm results
from gypsy_moth.  I did a little bit of trawling for other instances of
this coding pattern, and didn't find any; but if we turn up any more
of them I think we'd better revert the "char [4]" patch and find another
way of making tuptoaster.c alignment-safe.

to explicitly cast the output back to char before comparing it to a char
value, else we get the wrong result for high-bit-set characters.  Found by
Rolf Jentsch.  Also, fix several places where <ctype.h> functions were being
called without casting the argument to unsigned char; this is likewise
unportable, but we keep making that mistake :-(.  These found by buildfarm
member salamander, which I will desperately miss if it ever goes belly-up.

left in the code though it was not meant to be provided.  It represents a
security hole because unprivileged users could use it to look at (at least the
first line of) any file readable by the backend.  Fortunately, this is only
possible if the backend was built with XML support, so the damage is at least
mitigated; and 8.3 probably hasn't propagated into any security-critical uses
yet anyway.  Per report from Sergey Burladyan.

is also licensed to put a local variable declared that way at an unaligned
address.  Which will not work if the variable is then manipulated with
SET_VARSIZE or other macros that assume alignment.  So the previous patch
is not an unalloyed good, but on balance I think it's still a win, since
we have very few places that do that sort of thing.  Fix the one place in
tuptoaster.c that does it.  Per buildfarm results from gypsy_moth
(I'm a bit surprised that only one machine showed a failure).

by explicitly adding back the user to the DACL of the new process.
This fixes the failure case when executing as the Administrator
user, which had no permissions left at all after we dropped the
Administrators group.

and simpler, too.

"multi_call_ctx" to be a distinct sub-context of the EState's per-query
context, and delete the multi_call_ctx as soon as the SRF finishes
execution. This avoids leaking SRF memory until the end of the current
query, which is particularly egregious when the SRF is scanned
multiple times. This change also fixes a leak of the fields of the
AttInMetadata struct in shutdown_MultiFuncCall().

Also fix a leak of the SRF result TupleDesc when rescanning a
FunctionScan node. The TupleDesc is allocated in the per-query context
for every call to ExecMakeTableFunctionResult(), so we should free it
after calling that function. Since the SRF might choose to return
a non-expendable TupleDesc, we only free the TupleDesc if it is
not being reference-counted.

Backpatch to 8.3 and 8.2 stable branches.

Original patch from Hiroshi Saito, modified by me.

the files passed as argument.  This is desirable so that the dtrace rule
in src/backend/Makefile works.

a relevant error message instead of just dumping core.  Odd that nobody
reported this before Darren Reed.

ssh -L 3333:foo.com:5432 joe@foo.com

I think this should be changed to

ssh -L 3333:localhost:5432 joe@foo.com

The reason is that this assumes the postgres server on foo.com allows
connections from foo.com, which is not allowed by the default
listen_addresses setting.  Add more detail explaining this.

pointed out by Faheem Mitha

Also change the example port number 3333 to 63333 so no one can complain
that we are stealing a reserved port number.

These were previously only documented in the context of date/time formats.
