hello
try:
postgres=# select oprcode, oprleft::regtype, oprright::regtype from
pg_operator where oprname = '#';
oprcode | oprleft | oprright
---------------+----------+----------
path_npoints | - | path
box_intersect | box | box
poly_npoints | - | polygon
lseg_interpt | lseg | lseg
line_interpt | line | line
bitxor | bit | bit
int2xor | smallint | smallint
int4xor | integer | integer
int8xor | bigint | bigint
(9 rows)
so this means a xor operation
regards
