Ease of use

Clear, full, and accurate documentation exists as a result of a development process where documentation changes are required. Hundreds of small changes occur with each release that smooth off any rough edges of usage, supplied directly by knowledgeable users.

PostgreSQL works on small and large systems in the same way, and across operating systems.

Client access and drivers exist for every language and environment, so there is no restriction on what type of development environment is chosen now, or in the future.

The SQL standard is followed very closely; there is no weird behavior, such as silent truncation of data.

Text data is supported via a single data type that allows storage of anything from 1 byte to 1 gigabyte. This storage is optimized in multiple ways, so 1 byte is stored efficiently, and much larger values are automatically managed and compressed.

PostgreSQL has the clear policy of minimizing the number of configuration parameters, and with each release, we work out ways to auto-tune the settings.
