reasonable and it gets rid of the need for some entirely ad-hoc coding we
formerly used to reject bogus estimates.  The basic problem here is that
if the prefix is more than a few characters long, the two boundary values
are too close together to be distinguishable by comparison to the column
histogram, resulting in a selectivity estimate of zero, which is often
not very sane.  Change motivated by an example from Peter Eisentraut.

Refactor heap_page_prune so that instead of changing item states on-the-fly,

to accumulate the set of changes anyway to prepare a WAL record for the
pruning action, so this isn't an enormous change; the only new complexity is
to not doubly mark tuples that are visited twice in the scan.  The main
advantage is that we can substantially reduce the scope of the critical
section in which the changes are applied, thus avoiding PANIC in foreseeable
cases like running out of memory in inval.c.  A nice secondary advantage is
that it is now far clearer that WAL replay will actually do the same thing
that the original pruning did.

This commit doesn't do anything about the open problem that
CacheInvalidateHeapTuple doesn't have the right semantics for a CTID change
caused by collapsing out a redirect pointer.  But whatever we do about that,
it'll be a good idea to not do it inside a critical section.

Improve pglz_decompress() so that it cannot clobber memory beyond the
available output buffer when presented with corrupt input.  Some testing
suggests that this slows the decompression loop about 1%, which seems an
acceptable price to pay for more robustness.  (Curiously, the penalty
seems to be *less* on not-very-compressible data, which I didn't expect
since the overhead per output byte ought to be more in the literal-bytes
path.)

16 years agoThis patch addresses some issues in TOAST compression strategy that
Tom Lane [Fri, 7 Mar 2008 23:20:21 +0000 (23:20 +0000)]
This patch addresses some issues in TOAST compression strategy that
were discussed last year, but we felt it was too late in the 8.3 cycle to
change the code immediately.  Specifically, the patch:

* Reduces the minimum datum size to be considered for compression from
256 to 32 bytes, as suggested by Greg Stark.

* Increases the required compression rate for compressed storage from
20% to 25%, again per Greg's suggestion.

* Replaces force_input_size (size above which compression is forced)
with a maximum size to be considered for compression.  It was agreed
that allowing large inputs to escape the minimum-compression-rate
requirement was not bright, and that indeed we'd rather have a knob
that acted in the other direction.  I set this value to 1MB for the
moment, but it could use some performance studies to tune it.

* Adds an early-failure path to the compressor as suggested by Jan:
if it's been unable to find even one compressible substring in the
first 1KB (parameterizable), assume we're looking at incompressible
input and give up.  (Possibly this logic can be improved, but I'll
commit it as-is for now.)

* Improves the toasting heuristics so that when we have very large
fields with attstorage 'x' or 'e', we will push those out to toast
storage before considering inline compression of shorter fields.
This also responds to a suggestion of Greg's, though my original
proposal for a solution was a bit off base because it didn't fix
the problem for large 'e' fields.

There was some discussion in the earlier threads of exposing some
of the compression knobs to users, perhaps even on a per-column
basis.  I have not done anything about that here.  It seems to me
that if we are changing around the parameters, we'd better get some
experience and be sure we are happy with the design before we set
things in stone by providing user-visible knobs.
