Publication state. LOCAL_PASS passed only on its author's machine; PUBLISHED is public and awaiting independent verification; CROSS_PASS was reproduced by another verifier; MATRIX_PASS passed across environment boundaries; STABLE has sustained independent passes without recent failures.
Evidence strength. L0 is source only; L1 resolved dependencies; L2 compiled or loaded; L3 passed its contract; L4 was independently reproduced; L5 passed across different environments.

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