# PostgreSQL releases (for quite a long time) had the 3-component versions,
# where the first 2 components denoted a major version and the third one --
# the minor version. This has changed starting from version 10, with the major
# version represented by a single component. Minor releases are guaranteed to
# be backwards-compatible and contain only bug fixes. See also:
#
# https://www.postgresql.org/support/versioning/
#
# Note that the release version is not a semantic version and we will map it to
# the standard version as <major>.<minor>.0.
#
# There is no document that describes libpq ABI versioning and compatibility
# rules, so everything that follows is implied from
# src/interfaces/libpq/Makefile.
#
# The library naming schema on Linux is libpq.so.<so_major>.<so_minor>
# (SO_MAJOR_VERSION and SO_MINOR_VERSION in the Makefile) So presumably
# so_major is incremented on backwards-incompatible ABI changes (it hasn't
# been for the several last major version releases). And so_minor is equal to
# the package major version.
