Thread: Save postgresql node to catch only DML except delete queries

Save postgresql node to catch only DML except delete queries

Hi

I want to keep one slave node along with our production master server, but
that slave node only accept all the DML except Delete queries.

Primary purpose of this slave node is to keep all the data inserted to the
primary database and no need to delete any data from that.

Anybody know how to achieve this by using postgresql in-built support or
using any tool?

Thanks

/Pradeep.

Suggest you research logical replication solution such as Slony or
SkyTools.

You wil need to implement your own row firing triggers on  archiving
tables such that delets are a no-op.
