What's denoted as \t is not a tab character. It is a two character
sequence backslash followd by a t. I have tried all other possibilities
such as \\t , "\t", etc that I can think of, but I cannot get an honest to
god tab character to appear as field separator.
Yeah, that's a tough one. In bash you can use ANSI C quoting to pull
this off:
psql -c "select name,setting from pg_settings limit 1" -d postgres -At
-F $'\t'
See http://wiki.bash-hackers.org/syntax/quoting for more information.
Portability to other shells I'm not sure about.
Note that I did two other things a little differently than your example,
as well as tightening up the abbreviations:
-Putting the command in -c " " is just better all around than piping
into psql using echo. It even works with multi-line input, i.e.:
psql -c "
select 1
"
-Explicitly specifying the database manually using -d makes what's
happening easier to follow than expecting people to know the convention
that the first non-option passed to psql is a database name.
