This is a new error message. I have been using 1.10.0 (jun 29 2009, rev: 7942:7934M) for a number of weeks now, and I am just now seeing this error message. It only occurs the first time I ask the see a function. After that (even for other functions) it does not happen.
The server is Postgres 8.1.9, under Linux 3.2.3-58. 2009-07-20 08:14:09 STATUS : Retrieving Function details... 2009-07-20 08:14:09 STATUS : Retrieving Function details...
