pg syntax is :

COPY test (cola, colb, colc) FROM stdin;

...



this function doesn't let you in which order the columns are !

By default NULL values are a backslash followed with capital N ("\\N"). 



Also, you can't insert entries with OIDs (I've added it to my TODO list though)

Something needs to be said about the format of the array.

Judging by what I've seen, it's pretty much what you get

from loading a tab-separated file with file(). That is, the

lines are linefeed-terminated and there's no need to have

an extra line with "\.". On the other hand, when I try using this

command the connection to the server ends up in some odd

state and is then lost:

PHP Warning:  U�S�o() query failed: server closed the connection unexpectedly



I think it might be safer to use the lower-level function

pg_put_line() for now.

For starters, you can check the first line of every function document. It tells the minimum versions of PHP that you need in order to use the function.
