More cleanups of the include files - centralizing to simplify the -I's required to compile

/*-------------------------------------------------------------------------
*
Change my-function-name-- to my_function_name, and optimizer renames.
1999-02-13 18:22:53 -05:00
* lsyscache.h
Move get_attdisbursion to lsyscache. Clean up get_typdefault.

* Convenience routines for common queries in the system catalog cache.

Clean up handling of variable-free qual clauses. System now does the right thing with variable-free clauses that contain noncachable functions, such as 'WHERE random() < 0.5' --- these are evaluated once per potential output tuple. Expressions that contain only Params are now candidates to be indexscan quals --- for example, 'var = ($1 + 1)' can now be indexed. Cope with RelabelType nodes atop potential indexscan variables --- this oversight prevents 7.0.* from recognizing some potentially indexscanable situations.
