The following documentation comment has been logged on the website:
Page: https://www.postgresql.org/docs/16/sql-syntax-lexical.html
Description:
Hi,
Re. Docs page:
https://www.postgresql.org/docs/current/sql-syntax-lexical.html#SQL-SYNTAX-CONSTANTS-NUMERIC
I noticed that the following are specified as valid numeric constants:
1_500_000_000
0b10001000_00000000
0o_1_755
0xFFFF_FFFF
1.618_034
So I'd expect something like:
SELECT 1.618_034;
...to return 1.618034? But instead I get 1.618.
And:
SELECT 1_500_000_000::text;
...results in a: ERROR: syntax error at or near "::"
Which seems at odds to what the docs say:
"For visual grouping, underscores can be inserted between digits. These have
no further effect on the value of the constant."
I'm left not really understanding how to use _ in numerical constants?
Tim

You are reading the documentation for 16, but you are using 14 or lower.
If you want this functionality, you need to upgrade your server.
