[SQL] Cache lookup failure

[Najm Hashmi]

Hi All,
I am trying to do a simple insert, and I am getting cache look failure
error.
Could someone explain what causing it? My query and error are given
below:
fliprdb=# insert into collection(name, artist_id) values('El Baile
Aleman',2);
ERROR:  fmgr_info: function 24011: cache lookup failed
Thanks in advance for all your help
Regards
Najm
