Hey @ndeodhar I'm the author of TablePlus. Could you please show me the title of the connection?

Does it show YugaByte or something? TablePlus uses ctid in PostgreSQL to update the row, but YugaByte doesn't support it.

Hi @huyphams, TablePlus shows PostgreSQL title:

This is because we use PostgreSQL datatype while connecting to YB database. While we are compatible with Postgres, we have made changes to Postgres internals for YB. One example of this is changing ctid to a more YB specific ybctid.

We'd love to explore the possibility of building a custom integration for YugaByte with TablePlus. Let us know your thoughts.

Thank you for your clarification.
I can update the PG driver to support YugaByte easily if the select version(); return the driver name.
For example:
In PostgreSQL: select version() returns PostgreSQL 11.0;
it would be great if YugaByte returns YugaByte _version_number; So I can change the query based on that information.

That'll be great @huyphams, appreciate it!
Created this issue for us to update select version():#1841
TablePlus integration will also depend on: #1284.
