Hello,
I have been trying to use the pg_upgrade command to update a PostgreSQL
11 environment to 13 on macOS 11.
I have followed the steps in the documentation, but the command always
fails when trying to connect to the original database. This is the
command that is sent:
/Library/PostgreSQL/13/bin/pg_upgrade -b /Library/PostgreSQL/11/bin -B
/Library/PostgreSQL/13/bin -d /Volumes/Postgres_Data/PostgreSQL/11/data
-D /Volumes/Postgres_Data/PostgreSQL/13/data -p 49156 -P 49155 -U
postgres -j 24 -v
And this is what is logged:
connection to database failed: fe_sendauth: no password supplied
could not connect to source postmaster started with the command:
"/Library/PostgreSQL/11/bin/pg_ctl" -w -l "pg_upgrade_server.log" -D
"/Volumes/Postgres_Data/PostgreSQL/11/data" -o "-p 49156 -b -c
listen_addresses='' -c unix_socket_permissions=0700 -c
unix_socket_directories='/Volumes/Free/Upgrade'" start
"/Library/PostgreSQL/11/bin/pg_ctl" -w -D
"/Volumes/Postgres_Data/PostgreSQL/11/data" -o "" -m fast stop >>
"pg_upgrade_server.log" 2>&1
According to the documentation, the connection should be established
with the data in the .pgpass file. Its contents look like this (the
password has been changed) :
localhost:49155:*:postgres:password1234
localhost:49156:*:postgres:password1234
The .pgpass file works without problems with the pg_dump and pg_restore
commands, so I'm fairly certain its contents and privileges are set
correctly.
The PostgreSQL documentation also mentions that you can update the
pg_hba.conf file to use authentication method "peer". This has no effect
either, however when I set it to "trust", the command goes through just
fine.
So I have been able to do the upgrade, but I am still wondering why I
got the error in the first place. Any idea why the .pgpass file isn't
working with the pg_upgrade command?
Best regards,
Nick Renders
