Is an explicit disconnect required?

After running a script using pugsql, the following error messages are (always) in my database logs:

2021-01-01T05:50:02.596129Z 177181 [Note] Aborted connection 177181 to db: 'pmx' user: 'devv' host: '127.0.0.1' (Got timeout reading communication packets)
2021-01-01T08:05:02.745313Z 178061 [Note] Aborted connection 178061 to db: 'pmx' user: 'devv' host: '127.0.0.1' (Got timeout reading communication packets)
2021-01-01T10:36:29.269940Z 179043 [Note] Aborted connection 179043 to db: 'pme' user: 'devv' host: '23.143.154.21' (Got timeout reading communication packets)
2021-01-01T10:50:02.680148Z 179134 [Note] Aborted connection 179134 to db: 'pmx' user: 'devv' host: '127.0.0.1' (Got timeout reading communication packets)

This error might occur when a connection is not properly closed.
Should i execute explicit disconnects? If yes, than I could not find this in the documentation.

The database in use is MySQL.

Kind regards

Start by reviewing pugsql's connection lifecycle and any existing documentation, then compare it with the MySQL timeout messages shown in the issue. Done means determining whether callers must explicitly disconnect and documenting the confirmed behavior if the current documentation is incomplete.
