MultiPolygon is confused with ON

[Wilfred]

Given the SQL:

ALTER TABLE geoheader 
	ADD COLUMN geom geometry(MultiPolygon, 4269);

The parser produces:

source_file (0, 3) - (2, 0)
  alter_statement (0, 3) - (1, 25)
    ALTER (0, 3) - (0, 8) "ALTER"
    alter_table (0, 9) - (1, 25)
      TABLE (0, 9) - (0, 14) "TABLE"
      identifier (0, 15) - (0, 24) "geoheader"
      alter_table_action (1, 1) - (1, 25)
        alter_table_action_add (1, 1) - (1, 25)
          ADD (1, 1) - (1, 4) "ADD"
          COLUMN (1, 5) - (1, 11) "COLUMN"
          table_column (1, 12) - (1, 25)
