it would not work. A postgresql extensions holds a info about pg for it was compiled. So same version is explicitly required. The extensions uses a lot of internal not 100% immutable API usually - so it cannot work on different postgres.
Hi List, We are in need to use citext -case insensitive module from /contrib , we are running psql 8.3.6, would be safe to install the whole contrib package from 8.4.2 into this old version of PG db How about installing only citext package from 8.4.2 module into PG 8.3.6 will this work ? Thank you Isabella
