Log Message:
-----------
Now we have a caching mechanism for non-volatile (and non-SRF) procedures lays
in the TopMemoryContext. (Supports caching of triggers too.) Upper limit for
numbers of procedures to be cached are fixed with CACHE_MAX_SIZE definition. (In
case of a cache_size == CACHE_MAX_SIZE, the least used node will be removed from
the cache.) For cache lookup speed ups, a small CRC32 implementation with
supportive (and buggy) hash_init(), hash_buffer(), hash_arg_t(), hash_proc_t()
and hash_append() is added to produce procedure signatures.
