Current version of PostgreSQL JDBC Driver (42.3.1) does not support TCP_NODELAY option.当前版本的 PostgreSQL JDBC 驱动程序 (42.3.1) 不支持 TCP_NODELAY 选项。 But next version (42.3.2) will be supported.但将支持下一个版本（42.3.2）。
After 42.3.2 version you can use TCP_NODELAY option by adding 'tcpNoDelay=true' at the end of the JDBC URL like jdbc:postgresql://localhost:5432/postgres?tcpNoDelay=true After 42.3.2 version you can use TCP_NODELAY option by adding 'tcpNoDelay=true' at the end of the JDBC URL like jdbc:postgresql://localhost:5432/postgres?tcpNoDelay=true
