Thanks, Tom.
Locale is en_US.UTF-8.
Is there plan to alter that behavior to allow index in non C locale?
According to documentation: "However, if your database does not use the C locale you will need to create the index with a special operator class to support indexing of pattern-matching queries;"
So you'll have to create the index with a specific operator class.
CREATE INDEX tbl_col_text_pattern_ops_idx ON tbl(col text_pattern_ops) [1]
