Now I'm found following note in the DBD::Pg module documentation.

  NOTE: The undocumented (and invalid) support for the
  "SQL_BINARY" data type is officially deprecated. Use
  "PG_BYTEA" with "bind_param()" instead:

  $rv = $sth->bind_param($param_num, $bind_value,
                         { pg_type => DBD::Pg::PG_BYTEA });

[download]

Code seems to work OK after modification

$sth->bind_param(2, nfreeze($test), { pg_type => DBD::Pg::PG_BYTEA });

Thanks
