Running dsq in interactive modes more than once on the same file results in an error

[Joe Feeney]

I want to use dsq in the interactive mode -i, however, when I open the same file more than once with interactive mode dsq always fails to start interactive mode. It fails with the following error message: table "t_0" already exists.

• I'm able to produce this consistently with any valid csv file I pass to it.
• I have not tried other file types.
• I'm using whatever version of dsq is available on brew
• I've also validated that this behavior exists on main by building the source locally

Here's an example file I created and saved as test.csv

$ cat test.csv 
column1, column2, column3
a,b,c
d,e,f

The first invocation of dsq -i is usually successful, however, it emits this log line: Cache invalid, re-import required. even if I've never run -i before.

$ dsq -i test.csv       
Cache invalid, re-import required.
dsq> exit
EOF

All subsequent invocations of dsq -i test.csv fail with:

$ dsq -i test.csv
table "t_0" already exists

$ echo $?        
1

Removing the sqlite DB for that file allows me to run -i, however, with the same Cache invalid... log error as before:

$ rm $(dsq -D test.csv)
