I was thinking about it from the other angle -- clients that set
client_encoding and expect the server to do the conversion (e.g. the
JDBC driver) will see an error rather than bogus unconverted data.
What does the server currently do if you ask for a client_encoding that
isn't supported by the database encoding (e.g. LATIN1<->LATIN2)? It
seems to me that SQL_ASCII is kinda-sorta-if-you-squint-a-bit like an
encoding that doesn't support any client_encoding but SQL_ASCII.
