PostgreSQL has no single vendor, so the work centres on deciding who supports it and on building the high availability, backup and monitoring that a commercial database would ship with. It runs on any cloud or server, which makes it easy to keep data in an in-country region or data centre, and it is a common target when organisations in the UAE and Saudi Arabia move away from proprietary licences. ICU collations handle Arabic sorting, and we test search and ordering on real Arabic names before go-live.
A typical build pairs Patroni with a distributed configuration store for leader election, PgBouncer for connection pooling and pgBackRest for full, incremental and point-in-time backups. Logical replication lets us migrate with short cut-overs, Citus takes over when one node can no longer hold the data, and pgAudit with row-level security answers auditors who ask who saw which records.
