You cannot select the current database. A database connection remains
connected to the same database for the entire time of the connection.
You'll have to do what psql does: connect to the second database, and
if that succeeds, disconnect from the first one.
Where do I look for that code?
https://github.com/postgres/postgres/blob/master/src/bin/psql/command.c
As a starting point, section beginning with:
/*
* \c or \connect -- connect to database using the specified parameters.
*
* \c [-reuse-previous=BOOL] dbname user host port
...
Thank you.
Yours,
