Hi
I have a few questions:
1. Is there a simple way in postgresql 6.3.2 to implement a unique index on
one
field with null's allowed. So if the field is null it's ok else the value
must be unique?
2. I have copied the contents of a database ( ../data/base/name/* ) from one
computer to another computer. Is this in fact the way to copy databases?
After copying everything works except for example \dt , \di which gives the
following
error:
ERROR: cache lookup for userid 1003 failed
What does this mean?
