Parentheses issue when \copying to postgres from sqlite

[ptasheq]

Hi Folks,

using both 0.18.1 tag and current master branch I encountered the following issue:

Given chinook sample sqlite db is at /tmp/chinook.sqlite3 and the following table in postgres database is created:

create table genre(genre_id int generated by default as identity primary key, genre_name text);

I get the following unexpected results:

$ usql --version
usql 0.18.1
$ usql
(not connected)=> \set pgdb connection_string_to_postgres_db
(not connected)=> \set chinookdb sq:///tmp/chinook.sqlite3
(not connected)=> \copy :chinookdb :pgdb 'select GenreId, Name from Genre' 'genre';
error: failed to prepare query to determine target table columns: pq: syntax error at or near "WHERE"

(not connected)=> \copy :chinookdb :pgdb 'select GenreId, Name from Genre' 'genre(genre_id, genre_name)';
error: failed to prepare query to determine target table columns: pq: syntax error at or near ")"

(not connected)=> \copy :chinookdb :pgdb 'select GenreId, Name from Genre' 'genre(genre_id, genre_name';
COPY 25

Obviously, what I'd expect is the syntax error when the right bracket is missing.

More context:

$ go version
go version go1.22.2 linux/amd64

And I use Arch btw ;)

This is a bug in the postgres driver's Copy function, but the pgx driver has a different implementation. Can you try it out as a workaround until we can fix it?

The jokes are true! Arch rocks.
