Can anyone tell me what the data file names with the .1 .2 .3 etc.
extensions are? Are these undo versions of my tables or something? I
need to recover some disk space and I'm wondering if I need them. Here
is an example...
-rw------- 1 postgres postgres 1073741824 Oct 18 20:01 19523580
-rw------- 1 postgres postgres 1073741824 Sep 6 20:11 19523580.1
-rw------- 1 postgres postgres 1073741824 Sep 6 20:11 19523580.2
-rw------- 1 postgres postgres 1073741824 Sep 6 20:11 19523580.3
-rw------- 1 postgres postgres 1073741824 Sep 6 20:11 19523580.4
-rw------- 1 postgres postgres 1073741824 Oct 6 20:19 19523580.5
-rw------- 1 postgres postgres 629948416 Oct 19 12:33 19523580.6

Thanks, Bryan
