Tom Lane cf407f164e Refactor crosstab() to build and return a tuplestore instead of using
value-per-call mode.  This should be more efficient in normal usage,
but the real problem with the prior coding was that it returned with
a SPI call still active.  That could cause problems if execution was
interleaved with anything else that might use SPI.

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.
