Hi,
Commit 285613c60a7 added the min_protocol_version and max_protocol_version
connection options to libpq. However, their descriptions currently appear
in the middle of the unrelated ssl_min_protocol_version and
ssl_max_protocol_version entries in libpq.sgml. Is there a reason for
this placement?
To make the documentation more intuitive and easier to navigate,
I suggest moving these entries after the SSL-related options.
Attached is a patch that does that.
Thanks,

Subject: [PATCH v1] doc: Reorder protocol version option descriptions in libpq
docs.
Commit 285613c60a7 introduced the min_protocol_version and
max_protocol_version connection options for libpq, but their descriptions
were placed in the middle of the unrelated ssl_min_protocol_version and
ssl_max_protocol_version entries.
This commit moves the min_protocol_version and max_protocol_version
descriptions to appear after the SSL-related options. This improves
the logical order and makes it easier for users to locate the relevant
settings in the libpq documentation.
