Anyone know where to find documentation on this? Who knows what it escapes?
From PostgreSQL source (~/pgsql/src/interfaces/libpq/fe-exec.c):
8<-------------------------------------------------------------------- /* --------------- * Escaping arbitrary strings to get valid SQL strings/identifiers. * * Replaces "\\" with "\\\\" and "'" with "''". * length is the length of the buffer pointed to by * from. The buffer at to must be at least 2*length + 1 characters * long. A terminating NUL character is written. * --------------- */ size_t PQescapeString(char *to, const char *from, size_t length) 8<--------------------------------------------------------------------
I presume the PHP function is just a wrapper around this one (but did not actually check).
HTH,
