Yea, we could do that, but pg_dump seems like the wrong place to handle
this. For example, imagine if you have a mix of Win32 and Unix clients
--- if you create a function under Win32, it will look double-spaced to
a Unix client.

Ideally we would auto-convert the function text to the native client
format, but the function text is displayed via a SELECT, so how would we
special-case the function body SELECT output to output using the native
client line endings?

I am thinking we need a functions like unix_eol(), dos_eol(), or even
client_eol() to allow conversion of the output to an end-of-line format
matching the client. One nifty trick would be to modify the data type
of pg_proc.prosrc to auto-convert end-of-line format to match the
client. The problem there is that it special-cases a column just to fix
this single issue. Perhaps the ability to use functions like this is
the proper approach because they can be used in other places as well.
