Practical Guide: Azure PostgreSQL Migration and Tuning
A hands-on tutorial describing how the author completed the Microsoft Applied Skills assessment to configure and migrate to Azure Database for PostgreSQL Flexible Server. The post covers security and monitoring setup (Entra ID authentication, private endpoints, diagnostic settings), restoring an adventureworks sample database with a non-fatal PostgreSQL B-tree index row-size error, creating a cross-region read replica in Canada Central for a primary in Canada East, and query performance tuning using EXPLAIN and targeted index creation.
Practical, actionable guide for migrating and operating PostgreSQL on Azure; useful for cloud database operators and architects but not industry-shifting platform or policy news.

Key Takeaways & Evidence Grounding
- Author completed the Microsoft Applied Skills: Configure and migrate to Azure Database for PostgreSQL assessment and documented the steps.
- Configured dual authentication on Azure Database for PostgreSQL Flexible Server, enabling Microsoft Entra ID alongside native PostgreSQL authentication for server 'psql63693133'.
- Created a Private Endpoint ('psql63693133-pe') to isolate server traffic within VNET1/subnet1 and configured Diagnostic Settings to send PostgreSQL session logs to Log Analytics workspace 'loganalytics1'.
- Restored the 'adventureworks' sample database via pgAdmin and encountered a non-fatal PostgreSQL B-tree index row size error which caused only a secondary index creation to fail.
- Deployed a cross-region Read Replica ('psql63693133-replica') in Canada Central for a primary server in Canada East, and resolved a query bottleneck by creating index IX_Address_StateProvinceID on person.address(stateprovinceid).

Guide: Connect Power BI to PostgreSQL
This technical how-to explains connecting Microsoft Power BI to PostgreSQL databases for business intelligence, covering both local and cloud deployments. It walks through steps in Power BI Desktop (Get Data → PostgreSQL Database → enter server and database, authenticate, select tables), using Power Query to transform or load data, and creating model relationships (example joins between sales, customers, products, inventory). For cloud setups the guide uses Aiven for PostgreSQL: obtain host/port/db/credentials, download the CA SSL certificate, and enable SSL in Power BI to establish a secure connection. The article also highlights why SQL databases and SSL matter for reliable, scalable analytics and gives an example SQL aggregation query for pre-aggregation before visualization.
Guide: Connect Power BI to SQL Databases
This tutorial explains how to connect Microsoft Power BI to SQL databases, focusing on local PostgreSQL instances and managed cloud PostgreSQL provided by Aiven. It outlines steps in Power BI Desktop to open Get Data, choose PostgreSQL, provide server/database details and credentials, and load tables via the Navigator. For cloud-hosted Aiven PostgreSQL the guide highlights obtaining connection details, downloading and using an SSL certificate, entering connection parameters in Power BI, and loading tables to build a data model. The article also covers why SQL skills matter for querying, filtering, aggregation and table creation, and emphasizes the importance of building correct data models (primary/foreign keys) so Power BI calculations and joins work correctly.
PostgreSQL for Data Engineers: Indexes & Bulk Loads
This technical guide outlines practical PostgreSQL patterns for production data pipelines, focusing on operations that determine whether scheduled jobs succeed. It compares Python-to-Postgres loading methods (pandas.to_sql, psycopg2.execute_values, psycopg2.COPY) and recommends COPY for large backfills and execute_values for incremental writes. The article covers idempotent upserts with ON CONFLICT (including IS DISTINCT FROM to avoid unnecessary updates), index types and when to use B-tree, GIN, BRIN, partial and expression indexes, and how to read EXPLAIN ANALYZE. It also discusses window functions for time-series, CTE inlining behavior, JSONB indexing, pgvector for embedding search (HNSW vs IVFFlat), materialized views, table partitioning, routine maintenance (VACUUM/ANALYZE, autovacuum), practical pipeline schema patterns, and connection-pool settings for robust pipelines.
