you can do it, but don't do it! Escaping of large strings are not
cheap, processing extra long SQL statements are extreme expensive on
memory - so don't do it - or test it before and check memory and
processor usage - and check it in testing environment with more than
one user.

The good size for text or bytea is less than 100M and real max isn't
2G but it is 1G. LO isn't these limits because it isn't accessable on
SQL level.
