To me, this seems problematic as a general recommendation because
programs won't use this, and it's confusing to have different output
in psql than what your program sees. That's why I don't want to put
it into .psqlrc. The separate command will raise a few eyebrows here
and there. 8-/
Put differently, I think it's rather odd that in 9.0, both
encode(bytea_value, 'escape') and encode(bytea_value, 'hex') output
hexadecimal values. There's also an explicit way to request such
output, so I don't think that encode() should obey the bytea_output
setting. In 8.4's psql, a BYTEA column and its escape-encoded TEXT
were displayed differently, so there is precedent.
