PG Wire support

[KKould]

Feature Request

skip startup step

• Simple Query
• Extended Query

Question:
KipSQL is currently mainly used as an embedded SQL database. Its similar database may be SQLite, but SQLite does not support remote connections.
Therefore, it may be a bit redundant for KipSQL to support PG Wire?
However, if it is used to support operation and maintenance, it may be a good choice.

Tips:
This is a lower priority issue(I think)，Because there is no suitable answer in the Question part.
