Peter Eisentraut <peter_e@gmx.net>
Change the parser to convert SQL "position" and "substring" syntax to position() and substring() functions, so that it works transparently for bit types as well. Alias the text functions appropriately. Add position() for bit types. Add new constant node T_BitString that represents literals of the form B'1001 and pass those to zpbit type.
