Hi,
the OS here is openSUSE Leap 15.2. I downloaded the PostgreSQL 13.0 source and
built it without issues like so:
(pgTargetDir is /data/postgres/13.0)
$ ./configure \
--prefix=${pgTargetDir} \
--enable-nls \
--with-icu \
--with-perl \
--with-python \
--with-openssl \
--with-ldap \
--with-libxml \
--with-tclconfig=/usr/lib64
$ make install-world
As I said, no issues at all so far. Now, I set the new environment for version
13.0 and do:
$ initdb -D "${PGDATANEW}" \
-k \
--encoding=utf8 \
--lc-collate=en_US.UTF-8 \
--lc-ctype=en_US.UTF-8 \
--wal-segsize=32
Still, no issues and all is well.
Now comes the problem: I run pg_upgrade and it spits out problems with
plpython2:
$ pg_upgrade --check -k

Your installation references loadable libraries that are missing from the
new installation. You can add these libraries to the new installation,
or remove the functions using them from the old installation. A list of
problem libraries is in the file:
loadable_libraries.txt
Failure, exiting
$ cat loadable_libraries.txt
could not load library "$libdir/plpython2": ERROR: could not access file
"$libdir/plpython2": No such file or directory
In database: postgres
openSUSE has no python2 anymore, only python3. The source database does not
even have plpython installed:
postgres=# select name, version from pg_available_extension_versions
postgres-# where installed;
name | version
---------+---------
plperlu | 1.0
dblink | 1.2
plpgsql | 1.0
plperl | 1.0
(4 rows)
Can you please tell me what I am doing wrong here? Yes, I could compile the
source without Python in this particular case, because it is not needed on this
particular database cluster. But we have many more database clusters and a
bunch of them uses plpython, so I definitely need it. To better be safe than
sorry, I want the issue resolved before migrations start, even for database
clusters which don't need it.
Any help would be appreciated. Thanks very much in advance.
Cheers,
Paul
