The only problem I faced with Postgres SQL was that API people need column comments, and for a table with huge number of columns like 250-300 fields, it is very hard to update column via SQL query. And there is no provision in Postgres to tag comment to a column with DDL statement.

Senior Software Developer

One of my favorite features is that PostgreSQL can be learned quickly and easily because there are many resources, it has high performance, it can easily handle very large data operations and high instantaneous transaction loads.

I love using PostgreSQL for the following main reasons, firstly databases with a lot of data can be stored, it is possible to have different settings for various databases on a same server and on top that it costs nothing to use PostgreSQL since it is an open source software.

Postgres implements catalog internally, so it stores differently from other RDBMS(s).

PostgresSQL is very famous among the data engineering fraternity due to its high resilience and throughput.

PgAdmin is best tool to manage the DB with intuitive UI.

The query performance was identified and optimized with the use of the performance analysis tools, resulting in effective data retrieval.
