I've just had a look at a Linux install of 7.4.2 and the version
numbering that is present in the /lib and /bin directories. To make
things consistent, I would suggest the following approach for applying
version information on a per directory basis:
/bin - release numbering, e.g. 7.5.x
for all EXE/DLL
/lib - library numbering, e.g.
libpq.dll should be version 3.1,
libecpg.dll should be version
4.1 for all DLL
/lib/postgresql - release numbering, e.g. 7.5.x for all
DLL since these
DLLs are used internally by
the PostgreSQL server
There doesn't seem much point in versioning anything else.
To me, it makes more sense to version the libraries such as libpq.dll
like their UNIX-based counterparts so the version numberings are
consistent between the two. I can see a scenario using release numbering
where an application linked to libpq.dll could fail if it checked to
ensure the version matched the one it expected, even though an upgrade
would not always be necessary if the FE/BE protocol remained unchanged;
here the library numbering gives the better indication of the
capabilities of the DLL, since any changes in protocol behaviour would
be reflected by a change in the major/minor of the version number.
Incidentally I've just noticed from my Win32 build a couple of months
back that /lib and /lib/postgresql have been combined into /lib. Would
this make it more difficult to have different versioning schemes for
internal PostgreSQL libraries and the external client libraries as
