But you can do that with pg_encoding_to_char:

regression=# select pg_encoding_to_char(encoding) from pg_database where datname = 'template1';pg_encoding_to_char
---------------------SQL_ASCII
(1 row)

AFAICS the standalone pg_encoding program is only useful if you need to
do encoding-number conversions while the postmaster is not available.
