Argh, read the wrong line. Thanks for the correction. Still:
test=# select version();
version
------------------------------------------------------------------------------------
PostgreSQL 10.5 on x86_64-pc-linux-gnu, compiled by gcc (SUSE Linux)
4.8.5, 64-bit
(1 row)
test=# select 'abcd'||chr(8198) ~ E'abcd\s';
?column?
----------
f
(1 row)
When using E-syntax you need to double the backslash for escaping:
andreak@[local]:543310.4 andreak=# select 'abcd'||chr(8198) ~ E'abcd\\s';
┌──────────┐
│ ?column? │
├──────────┤
│ t │
└──────────┘

Hmm:
test=# show standard_conforming_strings;
standard_conforming_strings

off

test=# show escape_string_warning;
escape_string_warning
-----------------------
on
(1 row)
test=# select 'abcd'||chr(8198) ~ 'abcd\s';
WARNING: nonstandard use of escape in a string literal
LINE 1: select 'abcd'||chr(8198) ~ 'abcd\s';

Wonder if the OP has standard_conforming_strings='off' and
escape_string_warning='off'?
