Thank you Michael, I figured it was something fishy with the escaping.
When I try your example, I get
pgslekt=> select regexp_replace(
pgslekt(> '[p=1242|John Smith]',
pgslekt(> e'\\[p=(\\d+)\\|(.+?)\\]',
pgslekt(> e'<a href="./family.php?person=\\1">\\2</a>'
pgslekt(> );
ERROR: syntax error at or near " "
LINE 2: '[p=1242|John Smith]',
But with my own doctored code, it works just fine:
pgslekt=> select REGEXP_REPLACE(E'[p=1242|John Smith]',
E'\\[p=(\\d+)\\|(.+?)\\]',
E'<a href="./family.php?person=\\1">\\2</a>');
regexp_replace
---------------------------------------------------
<a href="./family.php?person=1242">John Smith</a>
(1 row)

The input is all my own from 127.0.0.1, so it's of course totally
trustworthy :-)
