Wiki / psql 命令

Lists operators with their operand and result types. If pattern is specified, only operators whose names match the pattern are listed. If one arg_pattern is specified, only prefix operators whose right argument's type name matches that pattern are listed. If two arg_pattern s are specified, only binary operators whose argument type names match those patterns are listed. (Alternatively, write - for the unused argument of a unary operator.) By default, only user-created objects are shown; supply a pattern or the S modifier to include system objects. If x is appended to the command name, the results are displayed in expanded mode. If + is appended to the command name, additional information about each operator is shown, including the name of the underlying function, and whether it is leakproof.
