Function array_to_string(text[], text) does not exist ???

[Johann Robette]

Hi,

I'm trying to call the array_to_string function like this :
SELECT array_to_string(array[1, 2, 3], '~^~') --> it comes
directly from the doc.
I get this error msg :
ERROR: parser: parse error at or near "[" at character 24

So I tried this way
SELECT array_to_string('{1, 2, 3}', '~^~')
I get this error msg :
ERROR: Function array_to_string("unknown", "unknown") does
not exist
Unable to identify a function that satisfies the given argument
types
You may need to add explicit typecasts

So I tried to cast it
SELECT array_to_string(CAST('{1, 2, 3}' AS _int8),
CAST('~^~' AS text))
I get this error msg :
ERROR: Function array_to_string(bigint[], text) does not
exist
Unable to identify a function that satisfies the given argument
types
You may need to add explicit typecasts

Any help would be greatly appreciated.

Thanks

What version of PostgreSQL are you running? According to the Release
Notes, array constructors and array_to_string() were added in 7.4.

Ok, that must be it.
In fact I was originally using 7.3 but I thought that we've upgraded to
7.4 but apparently note.

What I would do is upgrade it and it should work...

Thanls
