Fails to insert jsonb values in Postgres

We have a table with a field of type jsonb, which becomes string in the generated type, but it doesn’t seem to work when inserting a string with the json format, the exception I get is:

Npgsql.PostgresException (0x80004005): 42804: column "test" is of type jsonb but expression is of type text
Exception data:
    Severity: ERROR
    SqlState: 42804
    MessageText: column "test" is of type jsonb but expression is of type text
    Hint: You will need to rewrite or cast the expression.
    Position: 97
    File: parse_target.c
    Line: 588
    Routine: transformAssignedExpr

when trying to insert """{"publisher": "test"}""". Would you be able to help with this?

Oh, that’s genius 😄 I almost made it work with this new suggestion … will need to clean up the mess and open a PR in the beginning of the week. Yeah, I am enjoying the process, thanks for the help!

The plot thickens!

It seems that we may need to check for the existence of the column metadata attribute in the InsertExpressionBuilder and UpdateExpressionBuilder when record properties are being added.

The nice thing is that the LinqExpressionVisitors.visitPropertySelector returns MemberInfo that should give us the attribute metadata for free. So if any metadata exists, it can be added to the InsertQuerySpec or UpdateQuerySpec in the order at which the columns were added.

Then the QueryContext insert and update methods should have enough info to create a Map of parameter type info to the BuildCommand methods.
