Обсуждение: Is it possible to have psql ignore the line I am typing?

Hi everybody,

Is it possible to have psql ignore the line I am typing?
That is, similar to '#' with unix shell.  What I would
like is to document my interaction with psql.  If an
exclamation mark were a comment character, I may type
something like:

 silver=# ! I need to find out if data tagged as KIAA
 silver=# ! got into silver database last night.
 silver=#
 silver=# select type, name, marker
 silver-#   from marker_table
 silver-#  where tag LIKE 'KIAA%';

It would be nice to be able to jot down what little stream
of thoughts come to my finger tip while I converse with
psql.

Thank you in advance.

Regards,

Thank you, Rosser.

It is interesting to note that -- and "/* ... */"
have slightly different behavior.  Former is much
like # in shell or // in some programming languages,
while the latter shows multi-line propensity.

I believe the standard "--" remainder of line SQL comment glyph will work,
as should the C-style "/* ... */" block comment symbols.
