描述

Right now the error messages aren't very verbose with PostgreSQL when a migration fails, e.g.:

Failed with: syntax error at or near "."

It would be helpful to also display line/column position of the error in the file.

研究方向: Investigate how diesel currently handles migration errors, particularly the part where raw PostgreSQL error messages are displayed. Look at the `diesel migrations` crate and the `run migrations` function to understand the error flow. Consider using `PQresultErrorField` with `PG DIAG STATEMENT POSITION` to retrieve the line/column number from the server. Check existing comments for any suggested approaches or maintainer hints about acceptable implementation.
