Re: pg_ls_tmpdir to show directories and shared filesets

Hello Justin,

Some feedback about the v7 patch set.

About v7.1, seems ok.

About v7.2 & v7.3 seems ok, altought the two could be merged.

About v7.4:

The documentation sentences could probably be improved "for for", "used 
... used". Maybe:

   For the temporary directory for <parameter>tablespace</parameter>, ...
->
   For <parameter>tablespace</parameter> temporary directory, ...

   Directories are used for temporary files used by parallel
   processes, and are shown recursively.
->
   Directories holding temporary files used by parallel
   processes are shown recursively.

It seems that lists are used as FIFO structures by appending, fetching & 
deleting last, all of which are O(n). ISTM it would be better to use the 
head of the list by inserting, getting and deleting first, which are O(1).

ISTM that several instances of: "pg_ls_dir_files(..., true, false);" 
should be "pg_ls_dir_files(..., true, DIR_HIDE);".

About v7.5 looks like a doc update which should be merged with v7.4.

Alas, ISTM that there are no tests on any of these functions:-(
