[KYUUBI #6066] Fix PostgreSQL metastore migration script failure if indexes already exist

Browse Source 
# 🔍 Description
## Issue References 🔗

This pull request is a small fix for #5674

## Describe Your Solution 🔧

PostgreSQL support as backend for metadata store was added in #6027. If we choose it and run schema init scripts several times, then the following errors will be logged: `Error executing sql: CREATE UNIQUE INDEX unique_identifier_index ON metadata(identifier), with params: . ERROR: relation "unique_identifier_index" already exists`. This PR adds lacking `IF NOT EXISTS` to db indexes creation ddls in the PostgreSQL metastore init script.
