You can read? ;-)

You have to CAST the INT and the TIMESTAMP both into a STRING-typ, for
instance:

test=*# select 1::int || now()::timestamp;
ERROR: operator does not exist: integer || timestamp without time zone
ZEILE 1: select 1::int || now()::timestamp;
^
TIP: No operator matches the given name and argument type(s). You might need to add explicit type casts.
test=!# rollback;
ROLLBACK
Zeit: 0,124 ms
test=# select 1::text || now()::text;
?column?
