Обсуждение: 8.2.0 psql \df+ output mangled a bit relative to 8.1.4 ...

With a database loaded into 8.2.0 from a dump from an 8.1.4 server,
"\df+  foo()", where foo()'s body has embedded tabs shows up with
those tabs escaped, whereas under 8.1.4 they were emitted verbatim:

Is there a trick to getting old behaviour back? It seems to happen
regardless of client_encoding setting (either SQL_ASCII or latin1).
Thanks!

It's part of the aligned output patch. As you can see, it preserves the
alignment of the columns, whereas 8.1 did not.

Well, in unaligned mode it's still the old way. There was some
discussion at the time about whether tabs should be converted to spaces
on output, but I don't think that got anywhere...

It's a psql only thing BTW, other programs will not see it.

Have a nice day,

Many thanks!
