pg_escape_identifier - Escape a identifier for insertion into a text field

SYNOPSIS

       string pg_escape_identifier ([resource  $connection], string  $data)

DESCRIPTION

       pg_escape_identifier(3)	escapes  a  identifier (e.g. table, field names) for quering the database. It returns an escaped identifier string
       for PostgreSQL server. pg_escape_identifier(3) adds double quotes before and after data. Users should not add double quotes.  Use  of  this
       function  is  recommended  for  identifier  parameters  in  query. For SQL literals (i.e. parameters except bytea), pg_escape_literal(3) or
       pg_escape_string(3) muse be used. For bytea type fields, pg_escape_bytea(3) must be used instead.

       Note

	       This function has internal escape code and can also be used with PostgreSQL 8.4 or less.

		- A string containing text to be escaped.
