Обсуждение: major, minor and micro version

Hello,

is it possible to get the PG version splitted up into major, minor and
micro version in the future?
For now, only PG_VERSION is defined (at least, what i can see) and it is
not possible to use PG_VERSION at compile time to determine the actual
PG version.

Example:

In a module i want to use some of the new features from 8.0, but if the
user is compiling the module in a 7.x source tree, the old (but slower)
functions must be used (SPI_exec versus SPI_execute).


kind regards

This has been requested before, and while I don't remember whether the
petition has been accepted, I do remember that the customary workaround
was to use the CATALOG_VERSION_NO symbol from src/include/catversion.h.
This number is supposed to keep unchanged across a "major.minor"
release.
