Обсуждение: Rép. : double quotes around table and column names

The standard is that an identifier (table name, field name, ...) must be
double quoted if it contains any non (letter, digits, underscore)
character or if it is case sensitive

See User guide §1.1.1.

Again: use double quoted always or never.
Chose never if you can, eg if you use 'classical' table names

Use quoting if:
  - you want to build some very generic tool like an administrator
tool, a report generator...
  - if your app has some weird table names you cannot change

So my suggestion is the same as Mike's: avoid double quoting as much as
possible.

What is the suggested way of using double quotes around table and
column
names? Is there a standard or suggested usage?

Is that the SQL standard you are referring to? Because I use underscores
extensively without double-quotes with no problems.

I think he's saying if you use something OTHER than a letter, digit or
underscore you have to quote it, like

create table crazyname&*$#% ...

would fail, but

create table "crazyname&*$#%" ...

would work.
