契约

  1. assert pgx.ParseConfig parses PostgreSQL URI connection strings, extracting host, port, user, password, database, and runtime parameters
  2. assert pgx.ParseConfig parses keyword/value DSN connection strings into ConnConfig
  3. assert pgx.ParseConfig rejects malformed connection strings with an error
  4. assert pgx.Identifier quotes table, column, and schema names and escapes double quote characters with Sanitize
  5. assert pgx.CopyFromSlice iterates through row generators providing Next, Values, and Err for batch copy operations
  6. assert pgx.CopyFromRows constructs CopyFromSource from 2D slices and yields all rows sequentially
