Originally, this test created a 100000-row test table, which made it run rather slowly compared to other contrib tests. Investigation with gcov showed that we got no further improvement in code coverage after the first 700 or so rows, making the large table 99% a waste of time. Cut it back to 2000 rows to fix the runtime problem and still leave some headroom for testing behaviors that may appear later. A closer look at the gcov results showed that the main coverage omissions in contrib/bloom occurred because the test never filled more than one entry in the notFullPage array; which is unsurprising because it exercised index cleanup only in the scenario of complete table deletion, allowing every page in the index to become deleted rather than not-full. Add testing that allows the not-full path to be exercised as well. Also, test the amvalidate function, because blvalidate.c had zero coverage without that, and besides it's a good idea to check for mistakes in the bloom opclass definitions.

PostgreSQL is an advanced object-relational database management system that supports an extended subset of the SQL standard, including transactions, foreign keys, subqueries, triggers, user-defined types and functions. This distribution also contains C language bindings. PostgreSQL has many language interfaces, many of which are listed here: http://www.postgresql.org/download See the file INSTALL for instructions on how to build and install PostgreSQL. That file also lists supported operating systems and hardware platforms and contains information regarding any other software packages that are required to build or run the PostgreSQL system.
