The comments on this thread outline some reasons the permissions for LOCK TABLE are setup the way they are: http://archives.postgresql.org/pgsql-hackers/2010-11/msg01819.php Basically, if you have UPDATE, DELETE, or TRUNCATE privileges you can potentially lock out competing sessions on a table, similar to what some forms of LOCK TABLE would do; just having INSERT privileges doesn't necessarily give you that power.
