The version declared by the cygwin setup is 7.4-1 (I don't know if the '-1'
is the same that your '.1' or, for example, a progressive in the cygwin
PostgreSQL build sequence).
A 'select version()' answers with this information:
PostgreSQL 7.4 on i686-pc-cygwin, compiled by GCC gcc (GCC) 3.3.1 (cygming
special)
Are there other ways to get a better insight?
