I found a problem using Word 97 (and MSQuery) and Postgres: if the query
string put together by MSQuery is longer than 255 characters, it will add
a carriage return every 256 characters... this appears to be a generic
Word problem - I found vague references to it in the MS tech web site, and
a potential fix in Office 2000 SP1.

The symptoms were that MSQuery would complain "can't open the datasource"
- or some similar useless error. The errors from postgres were of the form
'error in SQL syntax' followed by some truncated-looking SQL. Typically
the error would be mismatched quotes. I watched the network during queries
and noted the extra line breaks.

Ironically, my workaround is to define a view which only returns the
fields I want so I can say 'SELECT * FROM my_view;', which is shorter than
255 chars, and seems to work ok.

I'd be surprised if this is what you're seeing, but it's worth a mention.
