Also make sure you're looking in the right database (using pg_relation_filepath instead may make this clearer). Remember that a given filenode/filepath also generates names with suffixes for forks (e.g. _vm) and segments (.1, .2 etc) - those need to be kept for valid filenodes and deleted along with orphaned ones. Naturally, if you get this wrong you will break your database beyond easy recovery, so BE CAREFUL. As an extra check, you could look at the times of the files and check against your server logs to see if there were indeed any crashes or unclean restarts of pg around those times; if you have a lot of apparently orphaned files you should investigate why. -- Andrew (irc:RhodiumToad)
