Do you think the TAP tests would benefit from having the input described in
a q(...) block rather than a string?

q(\if false
\echo a
\elif invalid
\echo b
\endif
\echo c
)


It's a lot more lines, obviously, but it might make what is being tested
clearer.

Commits

  1. Support \if ... \elif ... \else ... \endif in psql scripting.

  2. Add a "void *" passthrough pointer for psqlscan.l's callback functions.
