--- $Log$
--- Revision 1.7 2004/06/07 16:32:26 strk
--- Moved old version-specific sql files under the Attic directory.
---
--- Revision 1.5 2003/12/30 10:40:21 strk
--- For all versions:
--- Updated fix_geometry_columns to use a more readable format in queries.
---
--- For PG >= 73:
--- Updated fix_geometry_columns() to consider schema when fixing attrelid and
--- varattnum, also changed empty value to 'public' string for records with
--- an invalid schema specification.
--- Updated DropGeometryColumn to actually issue the
--- ALTER TABLE DROP COLUMN query.
---
--- Revision 1.4 2003/12/23 09:00:12 strk
--- AddGeometryColumn, DropGeometryColum moved to version-specific scripts.
--- Schema support enabled for version 73 and 74.
---
--- Revision 1.3 2003/12/18 18:07:06 strk
--- Changed fix_geometry_columns() for PG >= 73 so to set f_table_schema to
--- the empty string if its value is not a valid pg namespace.
---
--- Revision 1.2 2003/07/01 18:30:55 pramsey
--- Added CVS revision headers.
