More cleanups of the include files - centralizing to simplify the -I's required to compile
1996-08-27 21:59:28 -04:00
/*-------------------------------------------------------------------------
*
Change my-function-name-- to my_function_name, and optimizer renames.
1999-02-13 18:22:53 -05:00
* nodeFuncs.h
Move exprType(), exprTypmod(), expression_tree_walker(), and related routines into nodes/nodeFuncs, so as to reduce wanton cross-subsystem #includes inside the backend. There's probably more that should be done along this line, but this is a start anyway.

Extend the parser location infrastructure to include a location field in most node types used in expression trees (both before and after parse analysis). This allows us to place an error cursor in many situations where we formerly could not, because the information wasn't available beyond the very first level of parse analysis. There's a fair amount of work still to be done to persuade individual ereport() calls to actually include an error location, but this gets the initdb-forcing part of the work out of the way; and the situation is already markedly better than before for complaints about unimplementable implicit casts, such as CASE and UNION constructs with incompatible alternative data types. Per my proposal of a few days ago.

Another pgindent run. Fixes enum indenting, and improves #endif spacing. Also adds space for one-line comments.

New pgindent run with fixes suggested by Tom. Patch manually reviewed, initdb/regression tests pass.
