Fix for error at string to char* conversion in `executePreparedStatement` 

Dependency was throwing error 
`
template instance `arsd.postgres.PostgreSql.executePreparedStatement!(char, char)` error instantiating
`
when  use executePreparedStatement

DUB : 1.38.1
PostgreSQL: 16

I got this error in the package 

`
template `to` is not callable using argument types `!(string)(char)`
`
where the usage is ` db.executePreparedStatement("update_tbl_cmd",'3','a');`
