Fix encode(...bytea..., 'escape') so that it converts all high-bit-set byte

consider for example what happens if the text is transferred to another
database with a different encoding.  Decoding would then yield some other
bytea value than what was encoded, which is surely undesirable.  Per gripe

function (eg DecodeDateTime) has processed all the fields.  So, split the
BC adjustment and validity checks out into a new function ValidateDate that

Tom Lane [Tue, 12 Feb 2008 04:09:44 +0000 (04:09 +0000)]
Fix SPI_cursor_open() and SPI_is_cursor_plan() to push the SPI stack before
doing anything interesting, such as calling RevalidateCachedPlan().  The
necessity of this is demonstrated by an example from Willem Buitendyk:
during a replan, the planner might try to evaluate SPI-using functions,
and so we'd better be in a clean SPI context.

A small downside of this fix is that these two functions will now fail
outright if called when not inside a SPI-using procedure (ie, a
SPI_connect/SPI_finish pair).  The documentation never promised or suggested
that that would work, though; and they are normally used in concert with
other functions, mainly SPI_prepare, that always have failed in such a case.
So the odds of breaking something seem pretty low.

In passing, make SPI_is_cursor_plan's error handling convention clearer,
and fix documentation's erroneous claim that SPI_cursor_open would
return NULL on error.

Before 8.3 these functions could not invoke replanning, so there is probably
no need for back-patching.

Tom Lane [Mon, 11 Feb 2008 19:14:30 +0000 (19:14 +0000)]
Repair VACUUM FULL bug introduced by HOT patch: the original way of
calculating a page's initial free space was fine, and should not have been
"improved" by letting PageGetHeapFreeSpace do it.  VACUUM FULL is going to
reclaim LP_DEAD line pointers later, so there is no need for a guard
against the page being too full of line pointers, and having one risks
rejecting pages that are perfectly good move destinations.

This also exposed a second bug, which is that the empty_end_pages logic
assumed that any page with no live tuples would get entered into the
fraged_pages list automatically (by virtue of having more free space than
the threshold in the do_frag calculation).  This assumption certainly
seems risky when a low fillfactor has been chosen, and even without
tunable fillfactor I think it could conceivably fail on a page with many
unused line pointers.  So fix the code to force do_frag true when notup
is true, and patch this part of the fix all the way back.
