PgSql class

A description of a SQL query as interpreted by this package.

This includes the SQL string to send to the database and known data types for parameters, if any.

Queries can be sent to postgres as-is. To do that, pass a string to PgSession.prepare or PgSession.execute or use the default PgSql constructor. These queries are not intepreted or altered by this package in any way. If you're using parameter in those queries, you either have to specify their types in the PgSql constructor, or exclusively use PgTypedParameter instances in PgSession.execute, PgStatement.bind and PgStatement.run.

Alternatively, you can use named variables that will be desugared by this package with the PgSql.map factory.
