Proper SQL identifier parameterization in PostgreSQL loader#53
Conversation
Replace f-string interpolation of table and column names with psycopg2.sql.Identifier across all SQL construction sites in the PostgreSQL loader. This is the driver's own escaping logic and handles reserved keywords and special characters correctly. Also switches COPY from copy_from to copy_expert, which allows quoting both table and column identifiers via sql.SQL.

This PR addresses the concern raised by Aikido in #48 (SQL identifier concatenation) properly, and also covers the column quoting gap tracked in #52. Rather than a one-off regex validation, this uses psycopg2's built-in
sqlmodule which handles reserved keywords, schema-qualified names, and special characters correctly.Changes
psycopg2.sql.Identifiercopy_fromtocopy_expertso both table and column identifiers can beproperly quoted
Closes #52
