Re:

I'm trying to use the 'bit' and 'varbit' datatypes in a
table. The demo file 'varbit.demo.sql' runs fine but
when I
try to INSERT data into the table I get a message:

ERROR: zpbit_in: bit string of size 8 cannot be
written into
bits(1)

I can add data to the table through the console a la
demo
file though. I can also write one binary digit (i.e.
'B1')
using INSERT but I cannot write longer bit strings -
neither
can I find a way to make the type of the column to be
a
longer bit string. Any suggestions?

(I get the same problem with the varbit data type)

What version are you running? IIRC, there are types calling themselves
bit and varbit in 7.0, but they're only stubs; the first real support
for bitstrings is in 7.1.
