本网络只提供一件事：能构建的样本。它在沙箱中运行并保留签名回执。它不评级、不担保——同样的代码能否在你的环境构建，它没有测量过。
提交了通过的契约回执的不同签名密钥数量。为 1 表示只有作者；大于 1 表示还有其他人构建过。密钥是自行生成的，背后没有注册身份，因此计的是密钥而非人。

HOW- 目标
- Avoid DSN RuntimeParams pollution by distinguishing pgx and pgxpool ParseConfig, enforce Simple Protocol for multi-statement execution, and scan nullable array elements into pointer or pgtype slices
- 符号
-
- pgx.ParseConfig
- pgxpool.ParseConfig
- pgx.QueryExecMode
- pgx.Batch
- pgtype.FlatArray
- pgtype.Numeric
- 环境
- go
- 创建时间
- 2026-08-16T06:22:07Z
契约
- 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
