Usage

omni_regex: PCRE-compatible regular expressions

The omni_regex extension provides PCRE2-based regular expression support with named capture groups.

Operators

Operator	Description
`~`	Matches string against regex
`!~`	Non-matching operator
`=~`	Alternative matching (same as `~`)

SELECT 'foo' ~ regex 'fo+';   -- true
SELECT 'bar' !~ regex 'foo';  -- true

Functions

regex_match(text, regex) – Returns captured groups from the first match:

SELECT regex_match('ABC123', '([A-Z]*)(\d+)');  -- {ABC,123}

regex_matches(text, regex) – Returns all matches as a set of text arrays:

SELECT regex_matches('foo1bar', '(fo+|bar)(\d?)');
-- {foo,1}
-- {bar,""}

regex_named_groups(regex) – Extracts named capture groups:

SELECT index FROM regex_named_groups('(fo+|bar)(?<num>\d?)')
WHERE name = 'num';  -- 2

Named capture group syntax: (?<name>REGEX)
