How can you handle errors in PostgreSQL?
There are two main ways to address errors in PostgreSQL:
Callback functions can be developed to handle warning and error conditions. In this case, you can specify a certain behavior in case of errors and warnings in your queries using the WHENEVER command.
Detailed information about the error or warning can be obtained from the sqlca variable. This variable provides detailed information when errors and warnings arise during execution.

What is parallel querying in PostgreSQL?
Parallel querying is a technique in PostgreSQL that allows you to create query plans that can leverage multiple CPUs to answer queries more efficiently. This technique is particularly well-suited when the query involves scanning a lot of data but returning a few rows, for example, aggregate calculations.

PostgreSQL High Availability: The Considerations and Candidates
Almost every organisation that I interact with wants a high availability system for PostgreSQL. This clearly depicts an active trend toward an increase in utilising PostgreSQL for critical business applications.
