契约

  1. pgx.ParseConfig parses standard PostgreSQL connection URL and extracts host, port, database, user, password, and runtime parameters
  2. pgx.ParseConfig parses libpq key-value connection string and sets connect timeout
  3. pgx.ParseConfig returns an error for invalid connection strings
  4. pgx.NamedArgs rewrites named parameter placeholders into positional $1, $2 placeholders and orders arguments
  5. pgx.StrictNamedArgs returns error when SQL query references a parameter not present in map
  6. pgx.Identifier sanitizes and quotes single and multi-part SQL identifiers with quote escaping
  7. pgx.TxOptions defines transaction isolation level, access mode, and deferrable mode
  8. pgx.Batch queues multiple SQL statements and tracks batch length
  9. pgx.CopyFromRows and pgx.CopyFromSlice provide row iterators for bulk data copying
  10. Sample helper functions build sanitized SQL identifiers, parse connection configs, and rewrite named parameter queries
