results to contain uninitialized, unpredictable values. While this was okay as far as the datatypes themselves were concerned, it's a problem for the parser because occurrences of the "same" literal might not be recognized as equal by datumIsEqual (and hence not by equal()). It seems sufficient to fix this in the input functions since the only critical use of equal() is in the parser's comparisons of ORDER BY and DISTINCT expressions. Per a trouble report from Marc Cousin. Patch all the way back. Interestingly, array_in did not have the bug before 8.2, which may explain why the issue went unnoticed for so long. |

The PostgreSQL contrib tree
---------------------------
This subtree contains porting tools, analysis utilities, and plug-in
features that are not part of the core PostgreSQL system, mainly because
they address a limited audience or are too experimental to be part of
the main source tree. This does not preclude their usefulness.
User documentation for each module appears in the main SGML documentation.
Most items can be built with `gmake all' and installed with
`gmake install' in the usual fashion, after you have run the `configure'
script in the top-level directory. Some directories supply new
user-defined functions, operators, or types. In these cases, after you have
installed the files you need to register the new entities in the database
system by running the commands in the supplied .sql file. For example,
$ psql -d dbname -f module.sql
See the PostgreSQL documentation for more information about this
procedure.
