It's the bitwise 'and':
# \do+ &
List of operators
Schema | Name | Left arg type | Right arg type | Result type | Function | Description
------------+------+---------------+----------------+-------------+--------------+-------------
pg_catalog | & | bigint | bigint | bigint | int8and | bitwise and
pg_catalog | & | bit | bit | bit | bitand | bitwise and
pg_catalog | & | inet | inet | inet | inetand | bitwise and
pg_catalog | & | integer | integer | integer | int4and | bitwise and
pg_catalog | & | macaddr | macaddr | macaddr | macaddr_and | bitwise and
pg_catalog | & | macaddr8 | macaddr8 | macaddr8 | macaddr8_and | bitwise and
pg_catalog | & | smallint | smallint | smallint | int2and | bitwise and
(7 rows)
which doesn't seem appropriate in this context.
