Hi!
I need to escape double quotes only:
test=# select regexp_replace('"""{Performer,"Boomwacker ""a""
Recording""}"""', '([^"])"{2}([^"])', '\1\"\2', 'g');
regexp_replace
-------------------------------------------------
"""{Performer,"Boomwacker \"a"" Recording\"}"""
This is unexpected result.
But when added one symbol to ""a"" the result is right:
test=# select regexp_replace('"""{Performer,"Boomwacker ""a1""
Recording""}"""', '([^"])"{2}([^"])', '\1\"\2', 'g');
regexp_replace
--------------------------------------------------
"""{Performer,"Boomwacker \"a1\" Recording\"}"""
I had tested on versions:
PostgreSQL 9.5.1 on x86_64-pc-linux-gnu, compiled by gcc (Gentoo
4.8.3 p1.1, pie-0.5.9) 4.8.3, 64-bit
And:
PostgreSQL 9.5.3 on x86_64-apple-darwin, compiled by
i686-apple-darwin11-llvm-gcc-4.2 (GCC) 4.2.1 (Based on Apple Inc.
build 5658)
(LLVM build 2336.11.00), 64-bit
And:
PostgreSQL 9.4.7 on x86_64-unknown-linux-gnu, compiled by gcc
(Ubuntu/Linaro 4.6.3-1ubuntu5) 4.6.3, 64-bit
What`s wrong?
