We are not only missing a consensus about the terms noted here. There is
a bunch of terms where it is unclear which one is the 'official' or
'preferred' one. Two additional examples:
WAL / transaction logfile / XLOG file / log segment file / WAL
segment file
Log record / log entry
And there is a second problem: We have a common understanding of terms
like "cluster" or "database". But people coming from other DBMS may have
a different understanding.
A new PG user easily gets lost in the "term-jungle" used in our
documentation, in PG related books, blogs, and training material.
My proposal is to add an additional appendix to our documentation, where
fundamental terms and there meaning for the PG community are defined in
short and clear words (after we have found a consensus about them).
