Обсуждение: Better example
The following documentation comment has been logged on the website: Page: https://www.postgresql.org/docs/9.5/static/datatype-numeric.html Description: I think that in the section on floating point Infinity/-Infinity/NaN in the Data Types chapter the example would be better setting it to -Infinity rather than positive, as that would make clear that the minus sign needs to be within the quote marks. This isn't clear otherwise.
