These WAL records are then either copied to a second node as files (file-based log shipping), or directly streamed between nodes (streaming replication). No backups need to be taken and no downtime required (especially you are behind some pgbouncer or haproxy). Maybe under different tags. Adjust scripts using pg_stat_replication for new names (location changed to lsn), If you used pglogical as extension before version 10, you might need to adjust pg_hba.conf changing value between "columns", Adjust scripts for a new name of pg_log which is log, so something like find.

Basically for this method to be successful, you need to keep trying and fixing until the upgrade is successful. PostgreSQL replication usually relies on write-ahead logging (WAL), the process of logging data changes before writing them to disk.

In order to mock up the upgrade and thus to check if it's possible, you should build streaming replication or recover a standby server from WALs. The rest of the incompatible changes with previous releases are either too fresh to be referenced in lots of code (min_parallel_relation_size) or too ancient (external tsearch2) or are too exotic (removal of floating-point timestamps support in build), so we will skip them. The only difference is that we set POSTGRES_USER in our dockerfile for the convenience image: For this reason it won’t default to postgres regardless of whether the user sets the environment variable. socket. I'm not saying that Postgres is unworthy or that its adoption is fashion-driven -- it's part of the 5-10% that is driven by practicality.

Traditional dump/restore takes the longest time to complete and yet it is often a popular choice for those who can afford the downtime. The stable version of PostgreSQL 12 is scheduled to be released in late 2019. You can, of course, start "using" a new database before restore has finished (especially before all indexes are built - often the most time it takes is for indexes).

For example, you would want to pg_dumpall -g to get a list of needed roles to prepare in the new setup, or the opposite run pg_dump -x to skip permissions from old one.

If not, you have to modify the existing old cluster to eliminate any errors and start the process over again.
