bug#47357: 28.0.50; sql-list-tables: Executing SQL command... takes indefinite time after creation of new table

[Jean Louis]

I have noticed, but have not researched why, is that function
`sql-list-tables' takes indefinite time without completing or giving
result when I do following:

- M-x sql-postgres RET and more entries until I get into the SQL buffer

- create new table

- C-c C-l t with new table name is then taking indefinite time.

Maybe the library is reading tables only at initializations, I may be
wrong. In SQL buffer there is no problem to inspect the table, but C-c
C-l t does not allow it for new table created.

This may all be wrong and related to some other bug there, I do not
know. I was interrupting the indefinite message with C-g.
