I really don't think you want to do that. Base64 is used to make
binary data 7-bit safe for compatibility with legacy systems (i.e. to
embed arbitrary binary data within ASCII). Sometimes people escape
binary data as base64 to store it in their DB, but they typically
store it as bytea. Base64 probably isn't even a particularly good
choice for escaping binary, let alone storing it.
You should just use a generic escaping function. libpq has
PQescapeByteaConn(), for example.
