Custom Struct Tags

[ericsgagnon]

Is it possible to configure the struct tag for functions like StructToRowByName? I'm moving data between systems, so db isn't informative enough and has conflicts with other systems and packages. ie - I have structs that are used for multiple end points and multiple sources (like mssql, oracle, postgres) so db tag becomes an issue.

It's not externally configurable. Internally, it would be trivial to change.

const structTagKey = "db"

I suppose it could be made a public variable, but I'm generally not in favor of global configuration variables.

However, all the functions like RowToStructByName are simply implementations of RowToFunc. They don't have rely on any access to internal pgx functionality. You could copy the entire RowToStructByName type and change what you needed.
