Postgres ODBC driver versions On the Postgres ODBC driver page the name for each file is of the form:

psqlodbc_09_01_0100-x64.zip
psqlodbc_09_01_0100.zip
psqlodbc_09_01_0100-1.zip
psqlodbc_09_01_0200-x64.zip
psqlodbc_09_01_0200.zip
psqlodbc_09_01_0200-1.zip
psqlodbc_09_02_0100-x64.zip
psqlodbc_09_02_0100.zip


I'm trying to make sense of the file names, and haven't been able to find any documentation. The 09_01 is clearly the major/minor version and the x64 is pretty clear. What do the middle terms, like 0100-1 mean?
I found the following in the source code:


  This is version 07.05.0001. For those that don't know or don't
  recall how the versioning works, the major and minor number track
  the latest release of PostgreSQL that the driver is expected to work
  with. The revision number is a bit more complex. The first two digits
  are the version number, where even numbers are development versions,
  and odd are release. The last two digits are the build number.
  
  In other words, this driver is build 01 of development version 00, and
  is expected to work with PostgreSQL 7.5dev. :-) The leading zeros are
  an ODBC thing...


I guess one cannot get any better answer than this :)
