Summary:
Error with "?" parameter markers

Detailed description
When using a command with "?" parameter markers (like "select field from table where key=?;"), Prepare() emits an exception.

If the parameter has a name ("box" in this case), the exception's message and call stack are:

Parameter box not found in query.
in Npgsql.NpgsqlCommand.ReplaceParameterValue(String result, String parameterName, String paramVal) in C:\projects\Npgsql2\src\Npgsql\NpgsqlCommand.cs:línea 2865
in Npgsql.NpgsqlCommand.GetParseCommandText() in C:\projects\Npgsql2\src\Npgsql\NpgsqlCommand.cs:línea 2525
in Npgsql.NpgsqlCommand.Prepare() in C:\projects\Npgsql2\src\Npgsql\NpgsqlCommand.cs:línea 1583
in ...


If the parameter has no name (string.Empty in this case), or is created with none, the exception's message and call stack are:

Parameter Parameter1 not found in query.
in Npgsql.NpgsqlCommand.ReplaceParameterValue(String result, String parameterName, String paramVal) in C:\projects\Npgsql2\src\Npgsql\NpgsqlCommand.cs:línea 2865
in Npgsql.NpgsqlCommand.GetParseCommandText() in C:\projects\Npgsql2\src\Npgsql\NpgsqlCommand.cs:línea 2525
in Npgsql.NpgsqlCommand.Prepare() in C:\projects\Npgsql2\src\Npgsql\NpgsqlCommand.cs:línea 1583

Besides that, great development! Thanks!

Thank you, Josh! I've skipped that part of the user manual.

We support : and @ as parameter markers.
