As of postgresql 9.1 "standard_conforming_strings" is set to on

This will not work anymore
<?php
$copy_message = "1\t\\N\t300";
pg_copy_from($db, "message", $copy_message);
?>
result will be a "N" in that field. if the field allow text that is else it will fail to insert the post.

simple fix
<?php
$copy_message = "1\t\\NULL\t300";
pg_copy_from($db, "message", $copy_message, "\t","\\NULL");
?>

Fix for "Copy command failed: ERROR: literal carriage return
found in data" or
"Copy command failed: ERROR: missing data for column
"message" CONTEXT: COPY message, line 1:"

<?php
$message = "HEJ\rHEJ\nHEJ\r\nHEJ\n\rHEJ\tHELLO\\";

$message = addslashes($message);

$message = str_replace(
  array("\n","\r","\t"),
  array("\\n","\\r","\\t"),
  $message);

$copy_message = "1\t". $message ."\t300";

pg_copy_from($db, "message", $copy_message);
?>

This will not look in other schema's, only the schema's in your search path. You can temporarily change this behavior with the following code:

<?php
pg_query($conn, "SET search_path TO myschema;");

$copy_from = pg_copy_from($conn, 'tablename', $filetoarray, ",");
   
if ( !$copy_from )
{
    echo pg_last_error($conn);
       
    exit;
}

pg_query("RESET search_path;");
?>

see also: pg_put_line for a solution that does not require buffering of all the data to be copied,

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:  UåSèo() query failed: server closed the connection unexpectedly

I think it might be safer to use the lower-level function
pg_put_line() for now.
