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.

- PostgreSQL database connection resource. When $connection is not present, the default connection is used. The default connection
is the last connection made by pg_connect(3) or pg_pconnect(3).
o $data
- A string containing text to be escaped.
RETURN VALUES
A string containing the escaped data.
