• assert pgx.ParseConfig routes pool options into RuntimeParams while pgxpool.ParseConfig extracts them
• assert pgx.ParseConfig configures statement_cache_capacity and default_query_exec_mode without RuntimeParams pollution
• assert default QueryExecModeCacheStatement rejects multi-statement SQL strings while QueryExecModeSimpleProtocol succeeds
• assert scanning SQL arrays with NULL elements fails for []T but succeeds for []*T and []pgtype.Int4
• assert scanning SQL NULL array yields nil slice whereas SQL empty array {} yields non-nil slice
• assert pgtype.FlatArray flattens multi-dimensional PostgreSQL arrays into 1D Go slices
• assert pgx.Batch stops subsequent executions on query failure and BatchResults.Close returns the first error
• assert pgtype.Numeric handles fractional decimals, NaN, and Infinity modifiers without loss of precision
