but my question still remains the same - what causes pg_upgrade failure - are functions the reason? what I did was to delete these 2 rows from pg_pltemplate as I thought this may help:
postgres=# delete from pg_pltemplate where tmplname = 'plpython2u'; DELETE 1 postgres=# delete from pg_pltemplate where tmplname = 'plpythonu'; DELETE 1 but pg_upgrade still complains about plpython2: cat loadable_libraries.txt could not load library "$libdir/plpython2": ERROR: could not access file "$libdir/plpython2": No such file or directory In database: alaxx In database: template1 marcin@carbon2:~$ psql -U pgsql -h 192.168.89.64 alaxx psql (12.4 (Ubuntu 12.4-1)) Type "help" for help. argosrm=# select * from pg_pltemplate ; tmplname | tmpltrusted | tmpldbacreate | tmplhandler | tmplinline | tmplvalidator | tmpllibrary | tmplacl ------------+-------------+---------------+------------------------+--------------------------+---------------------+-------------------+--------- plpgsql | t | t | plpgsql_call_handler | plpgsql_inline_handler | plpgsql_validator | $libdir/plpgsql | pltcl | t | t | pltcl_call_handler | | | $libdir/pltcl | pltclu | f | f | pltclu_call_handler | | | $libdir/pltcl | plperl | t | t | plperl_call_handler | plperl_inline_handler | plperl_validator | $libdir/plperl | plperlu | f | f | plperlu_call_handler | plperlu_inline_handler | plperlu_validator | $libdir/plperl | plpython3u | f | f | plpython3_call_handler | plpython3_inline_handler | plpython3_validator | $libdir/plpython3 | (6 rows) argosrm=# \q marcin@carbon2:~$ psql -U pgsql -h 192.168.89.64 template1 psql (12.4 (Ubuntu 12.4-1)) Type "help" for help. template1=# select * from pg_pltemplate ; tmplname | tmpltrusted | tmpldbacreate | tmplhandler | tmplinline | tmplvalidator | tmpllibrary | tmplacl ------------+-------------+---------------+------------------------+--------------------------+---------------------+-------------------+--------- plpgsql | t | t | plpgsql_call_handler | plpgsql_inline_handler | plpgsql_validator | $libdir/plpgsql | pltcl | t | t | pltcl_call_handler | | | $libdir/pltcl | pltclu | f | f | pltclu_call_handler | | | $libdir/pltcl | plperl | t | t | plperl_call_handler | plperl_inline_handler | plperl_validator | $libdir/plperl | plperlu | f | f | plperlu_call_handler | plperlu_inline_handler | plperlu_validator | $libdir/plperl | plpython3u | f | f | plpython3_call_handler | plpython3_inline_handler | plpython3_validator | $libdir/plpython3 | (6 rows) what can I do next ?

Read that sentence again and see the inherent disconnect between the beginning and end. As a packager you are in charge of how the packaging is done. Still announcing a change that effectively nullifies the documentation would to me be something that should be announced somewhere else than a list that I'm guessing 99% of the users don't read. > > FWIW, older PostgreSQL major versions still have PY 2 support.
