Thanks. grep(1) and cut(1) make an adequate work-around.
Perhaps. Even with that, writing an extension for 9.2 would require
copy-pasting a lot of code from pg_controldata.c and taking as well the
code which has been introduced for the various control functions.
Dirty, still doable.
I've got some code which does just that to read pg_control as far
back as 9.3, and it is indeed not pretty ;).
