regexp_replace() function in new version

Hi,

regexp_replace() function in new version of PostgreSQL is giving error.

I am trying to remove tags from string.

I have tried following regex in & function:

- SELECT regexp_replace('<i>Abhijeet</b>',
'<(\s)*/?(?i:script|i|b|u|embed|object|a|frameset|frame|iframe|meta|link|style|table|th|td|tr|tbody|input|select|option|form|map|area|!--)(.|\n)*?>',
'\&\s');
- cc SELECT regexp_replace('<i>Abhijeet</b>', '<
*/?(?i:script|i|b|u|embed|object|a|frameset|frame|iframe|meta|link|style|table|th|td|tr|tbody|input|select|option|form|map|area|!--)(.|\n)*?>',
'\& ' );

*Both these try giving me error as follows*:

- WARNING: nonstandard use of escape in a string literal at character
42
HINT: Use the escape string syntax for escapes, e.g., E'\r\n'.
WARNING: nonstandard use of escape in a string literal at character
192
HINT: Use the escape string syntax for escapes, e.g., E'\r\n'.
ERROR: invalid regular expression: quantifier operand invalid

can anyone suggest me why is that error ocurring?
