sqlpage.run_sql opens a new database connection instead of reusing the connection over which the current request is being handled

sqlpage.run_sql fetches a new database connection from the connection pool instead of reusing the connection over which the current request is being handled

This has implications such as

• temporary tables not being accessible
• attached databases not being accessible
• performance

for details, see : #336

@guspower @vlasky v0.23 was released with the new single-connection setup for run_sql. Can you test and confirm it works as expected in your applications ?
