* Fix up memory management problems in contrib/xml2.Tom Lane2010-02-28
| | | | | | | | | | | | | | | | | | | | | Get rid of the code that attempted to funnel libxml2's memory allocations into palloc. We already knew from experience with the core xml datatype that trying to do this is simply not reliable. Unlike the core code, I did not bother adding a lot of PG_TRY/PG_CATCH logic to try to ensure that everything is cleaned up on error exit. Hence, we might leak some memory if one of these functions fails partway through. Given the deprecated status of this contrib module and the fact that errors partway through the functions shouldn't be too common, it doesn't seem worth worrying about. Also fix a separate bug in xpath_table, that it did the wrong things if given a result tuple descriptor with less than 2 columns. While such a case isn't very useful in practice, we shouldn't fail or stomp memory when it occurs. Add some simple regression tests based on all the reported crash cases that I have on hand. This should be back-patched, but let's see if the buildfarm likes it first.

* Allow predicate_refuted_by() to deduce that NOT A refutes A.Tom Lane2010-02-25
| | | | | | | | | | | | | | | | | | | | | We had originally made the stronger assumption that NOT A refutes any B if B implies A, but this fails in three-valued logic, because we need to prove B is false not just that it's not true. However the logic does go through if B is equal to A. Recognizing this limited case is enough to handle examples that arise when we have simplified "bool_var = true" or "bool_var = false" to just "bool_var" or "NOT bool_var". If we had not done that simplification then the btree-operator proof logic would have been able to prove that the expressions were contradictory, but only for identical expressions being compared to the constants; so handling identical A and B covers all the same cases. The motivation for doing this is to avoid unexpected asymmetrical behavior when a partitioned table uses a boolean partitioning column, as in today's gripe from Dominik Sander. Back-patch to 8.2, which is as far back as predicate_refuted_by attempts to do anything at all with NOTs.

* Allow zero-dimensional (ie, empty) arrays in contrib/ltree operations.Tom Lane2010-02-24
| | | | | | | | | | | | | | | | The main motivation for changing this is bug #4921, in which it's pointed out that it's no longer safe to apply ltree operations to the result of ARRAY(SELECT ...) if the sub-select might return no rows. Before 8.3, the ARRAY() construct would return NULL, which might or might not be helpful but at least it wouldn't result in an error. Now it returns an empty array which results in a failure for no good reason, since the ltree operations are all perfectly capable of dealing with zero-element arrays. As far as I can find, these ltree functions are the only places where zero array dimensionality is rejected unnecessarily. Back-patch to 8.3 to prevent behavioral regression of queries that worked in older releases.
