Thanks, Regina.

After uninstalling, I tried a fresh install of PostgreSQL followed by a
fresh install of PostGIS. The difference this time is that I did not use the
existing data structure and started with a new one. The installation went
well and without error.

I uninstalled then repeated the above process with my existing data
structure and got the same error as before. The data structure was created
using the 32 bit version of PostgreSQL/PostGIS:
postgresql-9.1.3-1-windows.exe (Not 9.1.4).

Is there an incompatibility between 64 bit and 32 bit data structures? Any
pointers appreciated.

Ah yes. Due to the different variable sizes between 64 and 32 bits, the underlying binary structures on disk will be different and therefore incompatible.


HTH,

Mark.
