I am getting the error...
ERROR: fmgr_info: function 0: cache lookup failed
...after creating a database, creating tables - indexes
and sequences, inserting data (with perl scripts) into 2 tables (570
records in one and 100 records in another), using "vacuum analyze" on
the database then trying "\d <tablename>" or "\dS". Running "vacuum"
alone is OK.
I run the query from psql.c:601 on the psql command line and get the
same result.
I tried the same sequence with a small test database and only a few
records and there were no problems.
I am still looking into this and would appreciate any pointers.
