I'm not really a tsearch user (just played with it a bit once). But I wondered 
if you are aware that you can prevent certain objects from being restored
quite easiy if you use pg_dump and pg_restore together with "custom format" 
(-Fc). There is some option to pg_restore that reads the dump, and ouputs a 
table of contents. You can then remove some entries from that list, and pass the 
modified list to pg_restore which will skip entries that do not show up on your 
modified list.

Maybe we could document some regexp, awk script, or similar that strips the 
tsearch stuff from such a table of contents?
