Hi,

I'm fairly new to postgresql, and I'm having some problems understanding
the syntax of SQL statements in psql. According to the documentation,
white space can be used freely. However, the following fails:

CREATE TABLE test
(
id Int8,
phenotype Varchar(510),
genotype Varchar(510)
);
testdb(> ERROR: syntax error at or near "Varchar"
LINE 4: phenotype Varchar(510),
^

where the field name and data type spec are separated by a tab
character. However, this works if the tab is separated by a single
space. Can someone please explain how this is controlled, and what the
proper syntax should be? Thanks in advance.

Cheers,

Thanks Joshua, that is the problem I wanted to illustrate; i.e.
whenever a tab separates the field name from the data type spec, the tab
character gets swallowed and psql cannot parse correctly. So it seems
tabs are not interpreted as simple white space, and it should not be
used in this case, am I right?

Actually that would make sense as psql supports tab complete so if the
terminal interprets a tab, it isn't going to treat it as spaces. I
would suggest changing your editor to treat tabs as 4 spaces.

But the problem still occurs with 'psql -f INPUTFILE', where tab
complete is irrelevant, so I'm confused.

You sure? I can't make the example fail that way. It does fail
when the example-with-tab is cut and pasted directly into a terminal
window, which is exactly as expected because that's exactly what
would happen if you interactively typed a TAB at that point. psql
doesn't see anything to complete with so it just beeps at you, without
adding anything to the input.

If you need to enter stuff like this interactively in psql, use -n
to disable readline.

You really shouldn't need -n to prevent tab completion in a -f file
though. If you can reproduce that then file a bug against whatever
version of readline you're using.

regards, tom lane
