The Popsink Postgres target connector consolidates transactional and analytical data in a PostgreSQL database while honoring your organization’s security and governance requirements.

​
Prerequisites

  • Roles and permissions: a PostgreSQL role with CREATE, INSERT, UPDATE, DELETE, and ALTER rights on the target schema, plus permission to execute functions required for COPY or INSERT operations.
  • Infrastructure settings: outbound network access from Popsink to port 5432 (or your custom port) with TLS enabled, root certificates imported, and PostgreSQL version 12 or later.
  • Quotas and limits: provision disk capacity for at least 150% of the expected daily volume and verify concurrent connection limits (max_connections) to accommodate Popsink workers.
  • Monitoring and audits: enable pg_stat_statements and error logging to trace connector activity.

​
Configuration

  • Batch ingestion
  • Streaming ingestion
1

Declare the destination

Provide the host, port, database, and target schema in Popsink. Attach a secret containing the user, password, and SSL string (sslmode=require) if needed.
2

Configure the write mode

Choose COPY for large volumes or INSERT for smaller datasets. Configure the maximum batch size (batch_size) and duplicate key handling (upsert_strategy).
3

Schedule loads

Define the sync cadence and retention rules for intermediate files. Ensure maintenance windows do not overlap with scheduled batches.

​
Monitoring

  • Instrument a dashboard built on pg_stat_activity, lock durations (pg_locks), and Popsink metrics (throughput, latency, errors).
  • Enable job failure notifications in Popsink and forward PostgreSQL logs to your SIEM.
  • Configure disk quotas and WAL usage alerts to prevent replication stoppages.

​
Best practices

  • Normalize data types (UUID, JSONB, timestamp with time zone) to avoid expensive conversions.
  • Document target tables with SQL comments to streamline maintenance.
  • Orchestrate schema changes outside of loading windows.
Avoid setting synchronous_commit=off on the Popsink session: if a failure occurs, you may lose transactions that were confirmed on the source.

​
FAQ

Enable upsert mode with ON CONFLICT DO UPDATE and use a versioning column (updated_at) to resolve collisions.
Declare the parent table in Popsink and ensure the PostgreSQL partitioning strategy routes rows automatically via triggers or PARTITION BY.
Start with Popsink logs to identify the failing step, then correlate with postgresql.log and pg_stat_activity for SQL details.

Understand metrics shared across all target connectors.
